Congressional Budget Office Report Dec. 05' -
http://www.cbo.gov/ftpdocs/69xx/doc6...ipbuilding.pdf Surface Combatants The Navy’s plan would buy seven DD(X) destroyers at a rate of one per year starting in 2007. Press reports indicate that the Navy hopes to reduce the cost of the first two ships of that class to $3.1 billion, with subsequent ships costing about $2.0 billion. CBO estimates that the cost of the first ship would be $4.7 billion and that the average cost for a seven-ship class of DD(X)s would be $3.7 billion (see Table 2). In addition, the Navy intends to begin buying a new missile-defense surface combatant, the CG(X) cruiser, in 2011. CBO assumes that a CG(X) would use the same hull—and cost about the same—as a DD(X) destroyer. However, the CG(X)s would have a lower average cost than the DD(X)s because more of them would be bought (19 between 2011 and 2023) and because some CG(X)s would be purchased at a rate of two per year, reducing their unit cost. The Navy’s 313-ship plan would also maintain a fleet of 62 Arleigh Burke class destroyers (DDG-51s). CBO assumes that those ships would be modernized and would serve for about 35 years, which is consistent with the Navy’s plan. Under that assumption, the first replacement for the DDG-51s—a DDG(X)—would need to be purchased in 2020.11 For this analysis, CBO assumed that the new DDG(X) would be somewhat larger than existing DDG-51s but smaller than DD(X) destroyers (since it would be unlikely to carry the advanced gun systems that DD(X)s have). In particular, CBO assumed the DDG(X) would displace about 11,000 tons at full load. In CBO’s projection, those replacement destroyers cost an average of about $2.2 billion apiece—the same cost per thousand tons as today’s Arleigh Burke destroyers—assuming that they are bought at a rate of three per year. Finally, CBO assumed for this analysis that the littoral combat ship would have a service life of 25 years, the midpoint of the Navy’s goal of 20 to 30 years. As a result, by 2030, the Navy would have to start buying large numbers of LCSs again to replace those purchased between now and 2017. Submarines |

Defense Acquisitions Evaluation of the Navy’s 1999 Naval Surface Fire Support Assessment September 1999 Page 3 : During the 1980s, the Navy spent about $1.7 billion to modernize and reactivate its four Iowa class battleships. During their reactivation, each of these ships was fitted with 16 Harpoon and 32 Tomahawk missile launchers, along with updated communications, fire control, and target acquisition systems. The estimated cost cited for reactivating the U.S.S. Wisconsin was $209.4 million and for the U.S.S. Iowa, was $221.3 million, including repair of the damaged turret. To accomplish the reactivation, the Navy estimated 14 months for industrial support and 3 to 6 months for modernization and training on and certification of newly installed equipment. The estimated cost of reactivating the U.S.S. Wisconsin was based on the actual cost to reactivate the U.S.S. New Jersey battleship in the 1980s, less the modernization costs that occurred during its reactivation, and escalating the figure to fiscal year 1999 dollars. The estimated cost of reactivating the U.S.S. Iowa is the same as the U.S.S. Wisconsin plus $12 to $14 million to repair the damage to the number 2 turret. Quote:

I, however would go with the Iowa's which should hold us over until the CG(X) bears some fruit. As you can see, DD(X) acquisition WON'T be complete until oh...2020. So by 2020 we'll have 7 DD(X)'s. Oh, and the program costs haven't gone down!! Again, I'll go for the Iowa's. For 5 billion. |

The estimated cost of reactivating the U.S.S. Iowa is the same as the U.S.S. Wisconsin plus $12 to $14 million to repair the damage to the number 2 turret. GAO-05-39R Options for NSFS November 2004 Page 4 : 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); * new combat and self-defense systems. Page 12 : 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; ------------------------------------------------------------- US Battleships 1935-1992 By William Garzke and Robert Dulin Revised Edition (1995) Foreword : Garzke & Dulin discuss several Phase II variants in pages 255-263 of their book, giving a cost estimate for each variant. Cost estimates are presumably in FY82 or FY83 dollar values. Variant 3A labelled as 'Small Helo' is similar to what they describe later in the books as 'Modest Upgrades' (pages 263-265) and similar to the BBG design proposed by USNFSA. Variant 7 labelled as 'Cost Constraint' is similar to the Phase 1 reactivation scheme actually carried out. As noted on page 263, the cost estimate for each alteration did not include such overhaul costs as the replacement of cabling and piping. Details for both variants below : Alteration Code 3A 'Small Helo' : Full-load Displacement, tons (m.t.) : 59,253 (60,211) Armament : * 16-inch/50 : 3-3-A-3 * 5-inch/38 : 12 * CIWS : 4 Missiles : * Tomahawk : 96 * SM-2 Standard : 0 * Harpoon : 16 * NSSMS : 4 Aircraft : 4 SH-60B Electronics : * Air Search : AN/SPS-49 * Surface Search : AN/SPS-67 * CIC : SYS-1/TFCC Hangar : Small Flight Deck : 1 Helo Complement : * Manning : 1,675 * Accommodations : 1,768 Cost (millions of $) : 700-900 Alteration Code 7 'Cost Constraint' : Full-load Displacement, tons (m.t.) : 58,504 (59,460) Armament : * 16-inch/50 : 3-3-A-3 * 5-inch/38 : 12 * CIWS : 4 Missiles : * Tomahawk : 32 * SM-2 Standard : 0 * Harpoon : 16 * NSSMS : 4 Aircraft : 4 SH-60B Electronics : * Air Search : AN/SPS-49 * Surface Search : AN/SPS-67 * CIC : SYS-1/TFCC Hangar : Small Flight Deck : 1 Helo Complement : * Manning : 1,722 * Accommodations : 1,817 Cost (millions of $) : 400-500 Alteration Code 7 'Cost Constraint' : Full-load Displacement, tons (m.t.) : 58,504 (59,460) Armament : * 16-inch/50 : 3-3-A-3 * 5-inch/38 : 12 * CIWS : 4 Missiles : * Tomahawk : 32 * SM-2 Standard : 0 * Harpoon : 16 * NSSMS : 4 Aircraft : 4 SH-60B Electronics : * Air Search : AN/SPS-49 * Surface Search : AN/SPS-67 * CIC : SYS-1/TFCC Hangar : Small Flight Deck : 1 Helo Complement : * Manning : 1,722 * Accommodations : 1,817 Cost (millions of $) : 400-500 1. Source #1 : Reactivation cost (i.e. rehabilitation + modernization) for all 4 Iowas during the 1980s was $1,700 millions in total, i.e. an average $425 millions per ship. This is close to the $400-500 millions estimate for Alteration code 7, which may suggest that rehabilitation costs were included in this estimate, and therefore also included in the cost estimate for alteration 3A. 2. Source #1 : The cost for rehabilitating the Iowas (i.e. reactivating without modernizing) was estimated at $209 millions in 1999 dollars. This would be equivalent to $120 millions in 1983 dollars based on inflation. This $120 millions is relatively consistent with the $170 millions for rehabilitation per Friedman, given that "the estimated cost of reactivating the U.S.S. Wisconsin was based on the actual cost to reactivate the U.S.S. New Jersey battleship in the 1980s, less the modernization costs that occurred during its reactivation, and escalating the figure to fiscal year 1999 dollars". 3. Source #2 : escalating the $210 millions estimate for 1999 with an annual 4% inflation rate yields a rehabilitation cost (i.e. reactivation without modernization) of about $250 millions. 4. Source #4 : modernization cost can be estimated for alteration code 3A by removing the rehabilitation cost from the overall cost estimate. Using Friedman's $170 millions for rehabilitation yields a modernization cost for alteration code 3A of $530-730 millions per ship in 1983 dollars, i.e. $1,000-$1,400 millions per ship in 2005 dollars. 5. Source #2 : an additional $110 million needed to replenish gunpowder for the 16-inch guns should be added to the total, i.e. about $50 millions per ship. Combining the above yields the following cost estimate in 2005 dollars for a reactivated BB with characteristics similar to Alteration Code 3A : * Rehabilitation : $250 millions per ship (per point 3.) * Modernization : $1,000-1,400 millions per ship (per point 4.) * Gunpowder replenishment : $50 millions per ship (per point 5.) => TOTAL : $1,300-1,700 millions per ship The above estimate does not include : a. some overhaul costs (see source #4); b. non-recurring costs for restoring the supporting infrastructure; c. R&D and manufacturing costs for developping and producing battleship-specific ammunitions that would meet the USMC requirements; |

The PMLRS option
Ok, an alternative NSFS idea,
Palletized MLRS (PMLRS): Remove the launcher components from your average M270A1. Mount them on a standard-sized pallet. Navalize where appropriate. This should produce a pallet of around 10' x 15-16' that could be transported by air, ship, truck, rail, whatever. They could even be moved ashore and fired from static positions. Create another pallet with fire control & operator stations. For the sake of argument, lets say each PMLRS has a program cost of $5 million (including dev, testing & some ratio of fire control pallets to rocket pallets). There's no way they'd cost that much, IMHO, since full-up M270A1s cost less than that, but I'd rather overestimate. Each PMLRS could carry the following [b]existing[/i] munitions, ready to fire, - 12 70km GMLRS (200lb unitary or DPICM) - 2 up-to-300km ATACMS (BAT, DPICM, 470lb unitary) or the following demonstrated growth munitions: - 12 100km GMLRS-ER (200lb unitary or DPICM) - 2 220km ATACMS-P (BROACH unitary penetrator) Add attachment points to the LCS helo deck for up to 4 PMLRS pallets, including power & C4 links. Offset them so all four can can be fired broadside in either direction, over a limited arc without obstruction. Store some number of reloads and a loader in the LCS hangers instead of aircraft. COmparison to Iowas: For the cost of just reactivating the two Iowas, $500 million, we could buy 100 PMLRS systems - enough to equip 25 LCSs with four each. That's up to 1200 GMLRS or 200 ATACMS rounds ready to fire out to a 70-300km range. Assuming one round per second per LCS, combined, they could fire all 1200 GMLRS missiles in 48 seconds! Try to match that with a pair of Iowas. In 48 seconds, they'd've just gotten their first salvo off - 18 rnds - and only to 24nm. Additional flexibility would come if you could continue air operations while mounting only one or two PMLRS per LCS. Two PMLRSs plus a pair of VTUAVs per LCS would allow each to search for & strike targets independently. Risks/Drawbacks: - Shipboard PMLRS might require a degree of stabilization, which increases costs & complexity. Guided rounds will mitigate this somewhat. - GMLRS-ER meets the threshold USMC range (41nm) but doesn't have the desired STOM range (200nm). ATACMS comes close, but it's expensive. (IIRC, GMLRS missiles are around the same cost as gun-fired PGMs like ERGM). USMC stud - Lack of Illum & smoke capability. Last edited by B.Smitty : 12-21-2005 at 14:58 PM. |

modern propulsion
You can probably drop this one from modernization as the propulsion systems, ie. boilers, turbines, jacking gear etc. for the four Iowa's are kept in very good condition in their cat"b" status. Any replacements on these may be either brand new or replaced from the two ships "AOE-1 Sacramento or AOE-2 Camden as they were mothballed in Sept 2004 or 2005 respectively. Both are at Bremerton, WA. Naval Yards to this day. Last edited by Dreadnought : 12-21-2005 at 13:48 PM. |

Probably would have a nice steady speed of...10 kts. Only capability is NSFS. Waste of money. Can't protect itself or engage naval or air threats. Your little raft would be a sitting duck. Only carries missiles and rockets. Aside from what you think, theres a development called the Free Electron Laser which when perfected will make 98% of rockets and missiles obsolete for attacking tactical targets. And theres a reason the DD(X) won't carry a MRLS system. And the munitions may exist, but then so do 16" shells and 155mm PGM's. Not to mention there isn't a naval fire control system configured for mrls. |

Besides, it fights as part of a team with Burkes, DD(X)/CG(X)s, subs and CVNs, so it'll hardly be a sitting duck. Quote:
In any event, these systems can still be saturated. And 1200 GMLRS in 48 seconds is far better than 36 16" rounds in a minute in this regard. Quote:
Guided 70-300km range 16" shells don't exist, not even in prototype form. 155mm PGMs exist but LRLAP does not. The exact GMLRS and unitary ATACMS rounds I mentioned above have been used in Iraq. The only ones that aren't fielded are the 100km GLMRS-ER and ATACMS-P. There doesn't need to be an existing naval fire control system configured for it. LCS contains large multi-mission areas where you can plug in palletized systems. I mentioned this in my description. Last edited by B.Smitty : 12-21-2005 at 18:42 PM. |

NAVTACMs was sucessfully fired from a Mk-41 VLS cannister in 1996. The program languished due to lack of funding after the Arsenal Ship concept was canned. Started back up in 03. Being planned for use in any ship with Mk-41s and the SSGNs Quote:
A feew months ago a joint Navy/Army ATACMs with a deep penetrator was tested. http://www.spacewar.com/news/missiles-05zzzh.html The Navy has jumped aboard the latest version of AFATDS. This so that DDX can accept fire missions from the same system that the rest of the fire support community uses. So ATACMs would be a "Plug and Play" item.
