Information on Options for Naval Surface Fire Support
Gao ID: GAO-05-39R November 19, 2004Land-, air-, and sea-based components form the "fires triad" that is used to support Marine Corps amphibious assault operations. The sea-based part of the fires triad is referred to as Naval Surface Fire Support (NSFS). The retirement of the last Iowa class battleship left a void in the NSFS part of the fires triad. To field a replacement NSFS capability, the Navy developed a two-phased plan in 1994. In the near-term to midterm, it would modify the capability of 5-inch guns on existing destroyers and cruisers, and develop extended-range guided munitions for the modified 5-inch gun. In the far term, it would field a sufficient number of new destroyers fitted with an even-longerrange advanced gun system and ultimately a very-long-range electromagnetic gun or "Rail Gun." However, in 1996, congressional authorizers became concerned that the Navy would not be able to produce a replacement NSFS capability comparable to the battleships until well into the twenty-first century. In that year's Defense Authorization Act, the Congress directed the Secretary of the Navy to restore at least two Iowa class battleships to the naval vessel registry until a capability was developed equal to or greater than that provided by the battleships. By 1999 the Navy had placed the Iowa and Wisconsin battleships back on the naval vessel registry and has been maintaining them in an inactive state since then. In recent years, the Navy's efforts to develop a NSFS replacement capability have not progressed as quickly as planned. Given concerns about the gap in NSFS capability, the Chairman, Subcommittee on Projection Forces House Committee on Armed Services requested that we review (1) the validated requirements for NSFS, (2) the estimated cost and schedule for reactivating and modernizing two Iowa class battleships to provide NSFS, and (3) the status of Navy efforts to develop a replacement NSFS capability.
The Navy and Marine Corps have only recently begun the process to establish validated NSFS requirements that address the overall capabilities needed and the balance between different systems that will be required to provide effective, continuous, and sustaining support fire for forces operating ashore. Validated requirements for some specific systems have been established, however. The cost and schedule for reactivating and modernizing two Iowa class battleships have not been fully developed. However, the Navy believes that reactivation of the battleships should not be pursued for a number of reasons. These include, among other things, manpower requirements and modernization needed to integrate the battleships into today's modern Navy. Therefore, the Navy has no plans to conduct the detailed studies needed to identify the full extent of needs and costs. The Navy's fielding of a replacement NSFS capability has been delayed. The near-term and midterm efforts to extend the range of munitions fired from the 5-inch guns on its cruisers and destroyers have been delayed from 2001 to possibly as late as 2011, but other program options have been discussed including the option of canceling or reducing the extended-range munitions program to fund development of another gun system. Far-term plans to help fill the NSFS gap by 2015 using a new destroyer with advanced gun systems were revised in 2001 to employ a different destroyer concept--the DD (X). The Navy currently expects sufficient numbers of DD (X) destroyers to be ready to help fill the NSFS gap by 2018 at the earliest.

November 19, 2004:
The Honorable Roscoe G. Bartlett:
Chairman, Subcommittee on Projection Forces:
Committee on Armed Services:
House of Representatives:
Subject: Information on Options for Naval Surface Fire Support:
Dear Mr. Chairman:
Land-, air-, and sea-based components form the "fires triad" that is
used to support Marine Corps amphibious assault operations. The sea-
based part of the fires triad is referred to as Naval Surface Fire
Support (NSFS). From World War II until the Persian Gulf War in 1991,
NSFS resided mainly in the capability of the 16-inch guns on the Navy's
Iowa class battleships. The thick armor of these battleships and the
24-nautical-mile range of their 16-inch guns gave the battleships
increased survivability in high-threat scenarios. The last Iowa class
battleship was decommissioned in 1992.
Their retirement left a void in the NSFS part of the fires triad. To
field a replacement NSFS capability, the Navy developed a two-phased
plan in 1994. In the near-term to midterm, it would modify the
capability of 5-inch guns on existing destroyers and cruisers, and
develop extended-range guided munitions for the modified 5-inch gun. In
the far term, it would field a sufficient number of new destroyers
fitted with an even-longer-range advanced gun system and ultimately a
very-long-range electromagnetic gun or "Rail Gun."
However, in 1996, congressional authorizers became concerned that the
Navy would not be able to produce a replacement NSFS capability
comparable to the battleships until well into the twenty-first century.
In that year's Defense Authorization Act,[Footnote 1] the Congress
directed the Secretary of the Navy to restore at least two Iowa class
battleships to the naval vessel registry until a capability was
developed equal to or greater than that provided by the battleships. By
1999 the Navy had placed the Iowa and Wisconsin battleships back on the
naval vessel registry and has been maintaining them in an inactive
state since then.
In recent years, the Navy's efforts to develop a NSFS replacement
capability have not progressed as quickly as planned. Given concerns
about the gap in NSFS capability, you requested that we review (1) the
validated requirements for NSFS, (2) the estimated cost and schedule
for reactivating and modernizing two Iowa class battleships to provide
NSFS, and (3) the status of Navy efforts to develop a replacement NSFS
capability. This letter summarizes our findings and transmits the
detailed briefing that we prepared for your staff. (See encl. I.)
To address our engagement objectives, we interviewed responsible
officials and reviewed official documents, including internal memos,
operational requirements documents, and related studies, from the
Marine Corps Combat Development Command, the Navy's Inactive Ships
Program Office, the Navy's Surface Warfare Directorate, the Navy's
Guided Projectile Office, the Joint Staff (J-8) Force Application
Assessment Division, and the U.S. Naval Fire Support Association. We
also toured the Battleship Wisconsin (BB-64) and the USS Winston
Churchill (DDG-81). We conducted our work from April through September
2004 in accordance with generally accepted government auditing
standards.
Results in Brief:
The Navy and Marine Corps have only recently begun the process to
establish validated NSFS requirements that address the overall
capabilities needed and the balance between different systems that will
be required to provide effective, continuous, and sustaining support
fire for forces operating ashore. Validated requirements for some
specific systems have been established, however.
The cost and schedule for reactivating and modernizing two Iowa class
battleships have not been fully developed. However, the Navy believes
that reactivation of the battleships should not be pursued for a number
of reasons. These include, among other things, manpower requirements
and modernization needed to integrate the battleships into today's
modern Navy. Therefore, the Navy has no plans to conduct the detailed
studies needed to identify the full extent of needs and costs.
The Navy's fielding of a replacement NSFS capability has been delayed.
The near-term and midterm efforts to extend the range of munitions
fired from the 5-inch guns on its cruisers and destroyers have been
delayed from 2001 to possibly as late as 2011, but other program
options have been discussed including the option of canceling or
reducing the extended-range munitions program to fund development of
another gun system. Far-term plans to help fill the NSFS gap by 2015
using a new destroyer with advanced gun systems were revised in 2001 to
employ a different destroyer concept--the DD (X). The Navy currently
expects sufficient numbers of DD (X) destroyers to be ready to help
fill the NSFS gap by 2018 at the earliest.
Validated Requirements for NSFS Overall Have Not Been Established:
The role of naval surface fire support has been evolving in tandem with
the Navy's amphibious assault doctrine, and for well over a decade,
since the decommissioning of the last of the Iowa class battleships,
both the Navy and Marine Corps have strived to address the specifics of
how to fulfill NSFS requirements. Until recently, these services have
had difficulty with reconciling their respective positions. Operational
requirements documents for several systems, such as the new destroyer,
that will contribute to the NSFS mission have been developed. On
several occasions, the Marine Corps has specified to the Navy what they
believe the replacement NSFS capability should be and the timing of the
capability. However, no single document has ever addressed the overall
capabilities and the balance between different systems that will be
required to provide effective, continuous, and sustainable supporting
fire for increasingly capable expeditionary forces operating ashore.
Although no formal NSFS requirement currently exists, in August 2004,
the Navy and Marine Corps agreed on an approach to correct the problem
by formally agreeing to develop an Initial Capabilities Document (ICD)
that would address the overall capabilities needed for naval fire
support. The goal of this ICD is to document and address the overall
capabilities required of naval fire support. This will assist in
determining the most effective and efficient balance of capabilities
and in determining the cumulative offensive power that naval forces
must be capable of generating. An integrated product team chaired by
the Marine Corps' Deputy Commandant for Combat Development office, in
coordination with the Office of the Chief of Naval Operations, will
conduct the required analyses, develop the ICD, and endeavor to gain
the Department of Defense's approval for the ICD.
Full Cost and Schedule for Reactivating and Modernizing Battleships
Have Not Been Analyzed:
To reactivate two Iowa class battleships to their decommissioned
capability, the Navy estimates costs in excess of $500 million. This
does not include an additional $110 million needed to replenish
gunpowder for the 16-inch guns because a recent survey found that it is
unsafe. In terms of schedule, the Navy's program management office
estimates that reactivation would take 20 to 40 months, given the loss
of corporate memory and the shipyard industrial base.
Reactivating the battleships would require a wide range of battleship
modernization improvements, according to the Navy's program management
office. At a minimum, these modernization improvements include command
and control, communications, computers, and intelligence equipment;
environmental protection (including ozone-depleting substances); a
plastic-waste processor; pulper/shredder and wastewater alterations;
firefighting/fire safety and women-at-sea alterations; a modernized
sensor suite (air and surface search radar); and new combat and self-
defense systems. Although detailed studies would be needed to identify
the full extent of modernization needs and costs, the Navy has no plans
to conduct these studies.
The Navy's program management office also identified other issues that
would strongly discourage the Navy from reactivating and modernizing
the battleships. For example, personnel needed to operate the
battleships would be extensive, and the skills needed may not be
available or easily reconstituted. Other issues include the age and
unreliability of the battleships' propulsion systems and the fact that
the Navy no longer maintains the capability to manufacture their 16-
inch gun system components and ordnance.
Delays in Fielding Replacement NSFS Systems After Retiring Battleships
Extend Gap in NSFS Capability:
Following the retirement of the last Iowa class battleship in 1992, the
Navy laid out a two-phase plan to provide a replacement NSFS
capability:
* The near-term and midterm phases called for modifying the 5-inch guns
on the current class of destroyers and cruisers planned for production
and developing extended-range guided munitions (ERGM) to be used in the
upgraded guns for improved range.
* The far-term phase called for developing a longer-range advanced gun
system to be fitted on a new destroyer and eventually a Rail Gun with
even greater range.
In the near-term and midterm, expected fielding of the ERGM system for
use in upgraded 5-inch guns on current destroyers and cruisers has been
delayed from 2001 to possibly as late as 2011. Technical and design
problems on the ERGM, which has been under development since 1996, have
led to test failures and delays.[Footnote 2] The Navy has awarded a
contract to a different company for developing an alternative
technology. The Navy now intends to issue a solicitation in 2005 to
hold full and open competition for development and low-rate production
for the extended-range munitions for the 5-inch gun. Other program
options have also been discussed to include canceling or reducing the
extended-range munitions program to fund the development of another gun
under consideration for the future destroyer called the "hypersonic
naval rail gun." Also, the Navy is considering the benefits of
installing modified 5-inch guns on the current cruisers to fire the
extended-range guided munitions. However, if undertaken, the Navy does
not intend to use these platforms in an NSFS role. This decision will
reduce the number of ships able to provide NSFS by 41 percent in those
scenarios where a 25-nautical-mile standoff range of the ships from the
shore is needed to protect them from shore-based threats. Without the
5-inch gun modification to handle the extended-range guided munitions,
the range of the cruisers' guns is only 13 nautical miles.
In the far term, the fielding of an advanced gun system has been
delayed. Initial plans called for fielding 32 new destroyers,
designated the DD 21, with advanced gun systems between 2008 and 2020
to fill the NSFS gap. In 2001, the Navy announced that it would replace
the DD 21 with another destroyer concept called the DD(X). The Navy now
expects to field 24 DD(X) destroyers between 2011 and 2023. A
sufficient number of DD(X) destroyers to help close the NSFS gap will
not be available until 2018. We reported that the ship's construction
plan was risky because some technologies are unproven and the design is
not yet stable.

Questions
1.What are the validated requirements for naval surface fire support
(NSFS)?
2.What are the estimated cost and schedule for reactivating and
modernizing two of the Iowa Class battleships to conduct naval surface
fire support?
3.What is the status of the Navy's efforts to develop a replacement
NSFS capability?
Naval Surface Fire Support
BACKGROUND
* "Fires TRIAD" supports Marine Corps amphibious assault operations.
* Fires TRIAD composed of complementary land (artillery/rockets), air
(aircraft), and sea (surface ship) components.
* Iowa Class battleships with their 16-inch guns were used for NSFS
between WWII and the 1991 Persian Gulf War.
* 1992 --Navy decommissioned last Iowa class battleship.
* FY92-93 --National Defense Authorization Act directs Secretary of
Navy to establish naval surface fire support R&D program
- Navy states that shift away from large caliber guns, the retirement
of the last battleships, and the current emphasis on amphibious assault
from over the horizon eroded capability to provide fire support for
forces ashore;
* - According to Navy this trend resulted in the congressional
direction that the Navy establish an NSFS R&D program.
* 1994 --Navy develops near-/mid-and far-term phased approach to
address current shortfalls in NSFS capability.
* 1995 --Navy removes the Navy's four inactive Iowa class battleships
from the naval vessel registry (NVR)
- NVR is the official inventory of ships and service craft in custody
or titled to the U.S. Navy.
* Ships remain on the NVR until they are disposed of.
* 1996 --Congressional authorizers were concerned that Navy's future
years defense program could not produce a replacement fire support
capability comparable to the battleships until well into the next
century. The National Defense Authorization Act of Fiscal Year 1996
directed the Secretary of the Navy to restore at least two Iowa class
battleships to the NVR
* Two battleships must be retained until the Secretary of the Navy
certifies that the Navy has within the fleet an operational surface
fire support capability that equals or exceeds the capability that the
battleships could provide if returned to active service.
* 1998/1999 --Navy placed the battleships Iowa and Wisconsin back on
the NVR
* According to Navy program management officials, maintenance costs for
the Iowa and Wisconsin totaled over $7 million for fiscal years 2000-
2004.
* Naval Surface Fire Support
Question #1 NSFS Requirements
* Question #1 - What are the validated requirements for naval surface
fire support (NSFS)?
* Past efforts to address NSFS requirements
* May 1992 --Navy's NSFS Mission Need Statement identified NSFS
shortfalls and listed several alternatives to address them.
* February 1993 --Navy begins development of Cost and Operational
Effectiveness Analysis (COEA) for NSFS
* Navy plans called for COEA to be followed by an Operational
Requirements Document (ORD) to provide detailed NSFS characteristics.
* October 1994 --Navy concludes that the assumed NSFS requirements
needed to be reevaluated and updated to guide NSFS plans.
* December 1994 - Chief of Naval Operations (CNO) approves revised NSFS
plan and in January 1995 directs that Navy initiate upgrades to the 5-
inch gun and develop precision-guided munitions for use in the modified
5-inch gun
* Initial operational capability before 2001.
* December 1994 - Navy signs memo transmitting COEA stating that
retirement of the battleships with their large caliber guns had eroded
Navy's capability to provide NSFS for forces ashore
* COEA proposed a variety of gun and missile weapon systems as
solutions to the NSFS requirement.
* November 1995 - Operational Requirements Document for an extended
range guided munitions for use in existing 5-inch guns signed.
* October 1996 --The Johns Hopkins University Applied Physics
Laboratory published NSFS Road Map Study Phase1report
* Report concludes that there was a need for a new vision to convey the
evolving role of NSFS--recommends that the Navy with the Marine Corps
and Army establish requirements for Navy fire support for the joint
land battle.
* December 1996 --Marine Corps Combat Development Command (MCCDC) memo
to CNO outlining NSFS requirements and their milestones
- NSFS is essential to augment organic fire support during the critical
early phases of an amphibious operation.
- NSFS initial operational capability by 2010 and a fully operational
capability by 2014.
- December 1996 MCCDC memo was followed by June 1999 and March 2002
memos to the CNO. The March 2002 memo
** reemphasized the Marine Corps requirements for NSFS stated in the
December 1996 and June 1999 memos.
* recommended establishment of a Capstone Requirements Document to
address NSFS requirements.
* November 1997 --DD 21 ORD signed
- One of the primary missions identified for the DD 21 was to conduct
NSFS.
- The first of 32 DD 21s to be procured in 2005 and entered into
service in 2010.
- In 2001 the DD 21 was replaced by the DD(X) destroyer
** Delivery of the first DD(X) has slipped to 2011.
* Marine Corps believes DD(X) with its Advance Gun Systems will help
meet their NSFS performance requirements.
* April 2002 --Navy informed Senate Armed Services Committee that they
concur with the Marine Corps position on NSFS requirements stated in
the March 2002 MCCDC memo.
* August 2002 --CNO reports to Congress that a dramatic improvement in
sea-based fires capability is required to align NSFS with Marine Corps
doctrine
- Report updates Navy's two-phased approach to provide NSFS support
** Near/mid term phase is projected to deliver the initial operational
capability of the ERGM for the 5-inch gun in 2005.
* Far-term approach is to develop a more robust set of NSFS weapon
systems for installation in the DD(X).
* Current efforts to address NSFS requirements
* February 2004 --ORD for Extended Range Munitions (ERM) signed.
* February 2004 - ORD for DD(X) destroyer signed.
* August 2004 --Marine Corps issues charter for an integrated process
team for development of the Initial Capabilities Document (ICD) -
"Joint Fires In Support Of Expeditionary Operations In The Littorals."
Charter states that
- A significant gap exists in Joint and Service capabilities associated
with naval fires and expeditionary warfare.
- No single document has ever addressed the overall capabilities - nor
the balance between different systems - that will be required to
provide effective, continuous, and sustainable supporting fires for
increasingly capable expeditionary forces operating ashore.
- Formally stating the overall capabilities required of naval fires
will assist not only in determining the most effective and efficient
balance of capabilities but ultimately in determining the cumulative
offensive fire power that naval forces must be capable of generating.
- Navy and Marine Corps agree that the ICD will be the basis for
resolving NSFS requirements issues.
* Marine Corps representatives believe that validated requirements will
help them compete with other programs for funding.
* Naval Surface Fire Support
Question #2 Battleship reactivation
* Question #2 - What are the estimated cost and schedule for
reactivating and modernizing two of the Iowa Class battleships to
conduct naval surface fire support?
* Full reactivation and modernization costs have not been analyzed
* Navy's 1999 estimate for reactivation cost was $430 million for both
ships.
* Reactivation would return the ships to their decommissioned
capability.
* Current cost to reactivate estimated to be in excess of $500 million
for both ships
- Cost assumption based on 1999 estimate with a 4% annual inflation
rate.
* Cost assumption does not consider availability of shipyard space to
complete the reactivation.
* $500 million reactivation cost does not include estimated $110
million needed to replenish gun powder for battleships' 16-inch guns.
* Recent survey found powder to be unsafe.
* The Navy has not conducted and does not plan to conduct studies to
define battleship modernization needs and costs.
* Navy program management office has identified the following as the
minimum battleship modernization improvements they believe would be
needed
- C4I (Command & Control, Communications, Computers and Intelligence)
equipment,
- environmental protection (including ozone depleting substances),
- plastic waste processor,
- pulper/shredder and gray (waste) water alterations,
- normal firefighting/safety and women-at-sea alterations,
- sensor suite (air and surface search radar),
- combat systems,
* self defense systems.
According to the Navy program management office, reactivation time has
increased
* 1999 estimate to reactivate battleships was 14 months.
* Current estimate of 20 to 40 months to reactivate the battleships.
* Increased reactivation time due in part to
- Loss of corporate memory.
* Shipyard industrial base.
* Time to modernize has not been estimated.
* Navy program management office lists reasons that would discourage
the Navy from battleship reactivation and modernization;
- Personnel - reactivation would require additional personnel that the
Navy does not have as well as significant training costs.
- Self Defense/C4SI - operation within modern battle group structure
would require significant upgrades.
- Propulsion - System is old, unreliable, potentially unsafe and
lacking skilled personnel.
- Ordnance - Navy no longer maintains capability to manufacture 16-inch
gun system components and ordnance.
- Cost - Estimate to reactivate both ships to their decommissioned
capability would increase to address modernization needs.
* Schedule - Loss of corporate memory and shipyard industry base
expected to increase reactivation time.
* Marine Corps supports the strategic purpose of reactivating two
battleships in accordance with the National Defense Authorization Act
of 1996 and supports the Navy's modernization efforts to deliver a
sufficient NSFS capability that exceeds that of the Iowa class
battleships
* Naval Surface Fire Support
Question #3 Replacement Capability
* Question #3 - What is the status of the Navy's efforts to develop a
replacement NSFS capability?
* In 1994 Navy developed plan to field replacement NSFS capability
* Near-/mid-term plan
- Modify capability of 5-inch guns on current destroyers and cruisers.
- Develop extended range guided munitions to fire in upgraded 5-inch
guns.
* Develop a long range land attack missile
* Far-term plan
- Develop and produce a new destroyer fitted with an advanced gun
system.
* Pursue electromagnetic technology (Rail Gun) with an even greater
range for the new destroyer
* Near-/mid-term plans to field replacement NSFS capability have
changed
* 1994 --Navy proposed a near-/mid-term NSFS plan that would upgrade
their 5-inch guns on current destroyers and cruisers and fit it with
extended range guided munitions
* 1996 - Navy awards contract to develop extended range guided
munitions (ERGM) system.
* Initial plans to field near/mid term replacement NSFS capability by
2001 were not realized on expected timeline because of technical and
design problems with the ERGM system.
* 1998 - Navy pursues development of a Land Attack Standard Missile
(LASM) to provide a long range missile capability by FY04 but the
program was terminated during FY03 budget development.
* October 2003 - Navy issues solicitation for alternative precision
guided munitions concept.
* May 2004 --Navy awarded a contract to a different company to develop
an alternative extended range munitions technology.
* June 2004 - Navy discusses options for accelerating Rail Gun
development to meet DD(X) schedule.
- According to Navy officials funding for Rail Gun research is
deficient.
* Options discussed to address funding deficiency included canceling or
descoping the extended range munitions program
* August 2004 - Navy again modifies plans for extended range munitions
for 5-inch gun
- Navy notifies industry of intent to issue a solicitation in 2005 for
System Development and Demonstration with a low rate initial production
option of precision-guided, extended range munitions to be fired in the
Navy's 5-inch gun.
* According to program official, depending on which system is selected,
initial operational capability could be as late as 2011.
* October 2004 - Navy is currently reconsidering decision to not put 5-
in guns on cruisers
- Even if cruisers receive new gun, the Navy does not intend to use
them in the NSFS role.
* Will reduce available NSFS capable platforms by 41 percent if 25
nautical mile stand-off range is adhered to.
* Concerns have been raised about sufficiency of far-term plans to
field replacement NSFS capability
* 1994 --Navy identified the need for a far term NSFS plan
- Plan evolved from the DD 21 to the proposal to develop the DD(X)
destroyer with advance gun systems.
** Current production plans call for sufficient DD(X) destroyers in
combination with DDG destroyers outfitted with extended range munitions
to fill NSFS gap by 2018.
** September 2004 GAO reported (GAO-04-973) that there is risk to the
DD(X) construction plan.
* Program plans to award the contract for detail design and
construction of the lead ship before the technologies are proven and
the design is stable
* Current NSFS gun range capability falls short of Marine Corps stated
range requirement
* Marine Corps 2002 memo to CNO lists the following near term NSFS gun
range requirement
- Desired/Objective - 63 nautical miles from ship to shore.
* Minimal Acceptable/Threshold - 41 nautical miles from ship to shore
* Current NSFS guns are not able to achieve Marine Corps stated NSFS
gun range requirements when ships are positioned 25 nautical miles from
shore due to increased land based threats
- The 5-inch guns with a range of 13 nautical miles currently in use on
destroyers and cruisers unable to meet range objective.
** Desired/Objective range could be met with anticipated increase in
range using ERGM currently in development.
* The 16-inch guns with a range of 24 nautical miles used on
battleships unable to meet range objective when 25-nautical-mile
standoff range is required
- Minimal Acceptable/Threshold range to target could be achieved if
battleships operated closer to shore.
* Desired/Objective range to target could be achieved with previously
tested but not fielded advanced projectiles.
* Recent Navy analysis found that the need for replacement NSFS
capability continues to exist
* Navy officials stated that their analysis confirms a capabilities gap
exists during the early stages of a conflict.
* Analysis confirms that ships are best gap filler based on
- Immature theater;
- Lack of air superiority;
- Capacity;
- Number of people placed in danger;
- All weather;
- Capability (24 hours/7 days per week);
* Cost.
* Summary
* Marine Corps and Navy have had difficulty reconciling their positions
for formalizing NSFS requirements.
* Recent agreement to have a Navy/Marine Corps developed Initial
Capabilities Document expected to eventually result in validated NSFS
requirements.
* Full battleship reactivation and modernization costs have not been
analyzed.
* Gap in NSFS capability since retirement of the battleships expected
to continue until end of next decade or later
- NSFS replacement capability has not progressed as quickly as planned.
** Plans for improved 5-inch gun near/mid term NSFS replacement
capability delayed from 2001 to possibly as late as 2011.
** Marine Corps states that DD(X) with advance gun systems will help
meet their NSFS needs.
** Plans for DD(X) far-term NSFS replacement capability will not be
achieved until 2018 or possibly later.
