The sonar array of the flight three boats is a the most radical design change of a U.S. submarine sonar in ~50-years. <br /><br />GABAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-77906279226740290622014-01-04T12:41:35.708-08:002014-01-04T12:41:35.708-08:00GAB,

We only built three. All the up-front' costs (R&D, spare parts) are levied onto that small denominator. The end result is an artificially unit cost.<br /><br />In contrast, we've since built ten VIRGINIA class and have eight more laid down or under contract. All the up-front costs for VIRGINIA get spread out over a larger denominator.<br /><br />It's interesting to Imagine if the Navy had stuck SEAWOLF class back in the '90s - and gone into true serial production. The unit cost likely could've gone down quite substantially. <br /><br />MattAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-48672185196443743982014-01-04T11:37:01.083-08:002014-01-04T11:37:01.083-08:00ComNavOps
Fair enough on the weapons.
Reference ...ComNavOps<br /><br />Fair enough on the weapons.<br /><br />Reference costs: <br /><br />"In FY 2005 dollars, SSN-21 submarines cost between $3.1-3.5 billion each."<br /><br />http://www.defenseindustrydaily.com/Virginia-Class-Sub-Program-Wins-Acquisition-Award-05167/<br /><br />zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz<br /><br />So like I said, back in the 1990s, when the funding decisions were made, Seawolf was much more expensive than the Virginia boats. Again:<br /><br />Seawolf cost $2.4 billion in *FY 1997 dollars*.<br /><br />Virgina cost $2.0 billion in *FY 2005 dollars*.<br /><br />When you adjust the costs to FY 2005 when USS Virginia was commissioned in 2005: Seawolf cost over $3 billion dollars, and the flight one Virginias came in at just over $2 billion per copy in *FY 2005* dollars. Ergo Virginia boats cost 2/3rds the cost of a Seawolf in FY 2005 dollars.<br /><br />There is no smoke and mirrors reference costs: you have to adjust for inflation. <br /><br />The SSN774 program is now going into its third design, basically improving performance at each stage (well we will see how flight III works), greatly adding weapon capacity (VPM), radically shortening the actual construction time of each boat, and roughly holding costs constant in FY 2005 dollars.<br /><br />How good is Virgina versus Seawolf: well that is the question, and one that anyone not intimately connected with the submarines is unlikely to know.<br /><br />That said, Seawolf was not without its issues, and got dinged up by GAO for construction problems and issues with its combat systems.

The very brief list of torpedo capacities was just a passing reminder and was in no way a capabilities comparison. The post was not a comparison of Seawolf and Virginia in any way other than the mention that Virginia was intended to be a lower cost alternative.<br /><br />As far as cost numbers, I'm using RAdm Butler's figures from the Proceedings article that I referenced in the post. Here's the relevant quote:<br /><br />"All told, each boat's final cost increased by approximately $1 billion on average and, over the 30-ship program, the total obligation authority went from approximately $60 billion in the mid-1990s to $90-plus billion in the mid-2000s."<br /><br />That means that the TOA of $90B over 30 ships = $3B. Subsequent cost reduction programs reduced that to $2.5B per ship.<br /><br />RAdm Butler was PEO Submarines. His numbers ought to be as reliable as can be had in the public domain. If you have a better source, I'll be glad to consider it.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-84384355779718112342014-01-03T15:16:47.995-08:002014-01-03T15:16:47.995-08:00Seawolf cost $2.4 billion in *FY 1997 dollars*.

An this does not begin to address the really important features like sensors. We will not know how well Virginia flights compare with Seawolf (which has also most certainly been updated)<br /><br />GABAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-57540516288117896682014-01-03T10:30:06.538-08:002014-01-03T10:30:06.538-08:00GAB, to be fair to me, I offered little explicit c...GAB, to be fair to me, I offered little explicit criticism of costs in the post. I noted that the original intent of being a low cost alternative to the Seawolf class was a failure. That's a criticism and seems a fair one. Wiki reports the projected costs of 12 Seawolfs as $2.8B each. Compared to the Virginia's costs of $2.5B, even allowing for inflation, that seems a failed "cheap" alternative. Beyond that, I simply noted the costs.<br /><br />I further stated that the serial production and MYP cost savings did not seem to be evident though they may be present but swamped by the flight cost increases, as you note. The 2012 to 2018 cost increases appear to be simple inflation. That's not a criticism, just an observation of the data.<br /><br />By Navy standards, which are abysmally low, the Virginia is a stable program with controlled costs. Now that is an implied criticism but it's also a fair statement, I think!<br /><br />Was there a specific aspect of costs that you think I've been unfair about?<br /><br />Here's an amusing insight into the Navy's thought process... In the Proceedings article, the author notes that the original cost of the Virginias ballooned by $1B per sub. The Navy then embarked on a massive cost cutting exercise and reduced the increase from $1B to $500M. The author then wrote an article praising the Navy's outstanding fiscal management of the program for the highly successful cost cutting (his thoughts, not mine). He seems oblivious to the fact that the net result was a $500M increase. The Navy touts the Virginia program as a shining example of acquisition success despite failing in its stated intent to be a low cost alternative, racking up a half billion dollars of overrun per vessel, and failing to demonstrate any serial production or MYP savings (again, they may be there but swamped by other cost increases). The Navy's idea of success is what most of us would consider failure.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-24602387653035783042014-01-03T06:58:46.046-08:002014-01-03T06:58:46.046-08:00ComNavOps,

In the past these were different ship classes, but alongside the inane Navy ship naming scheme, we seem to have adopted the software industry system of using versions rather than classes.<br /><br />Second, you must account for both inflation, and constant year cost comparisons. Accounting for modest inflation, your 2012 to 2018 numbers look reasonable. <br /><br />GABAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-3477152110072337992013-12-31T17:05:26.775-08:002013-12-31T17:05:26.775-08:00Kind of makes one wonder if we just shouldn't ...Kind of makes one wonder if we just shouldn't have stuck with the Seawolf. How much did we really save by going Virginia class? or was it just a political/navy strategy to fund only 3 Seawolfs and go to the "cheaper" model,even if it really wasn't that much cheaper?NICOhttps://www.blogger.com/profile/14567491909555759918noreply@blogger.com
