Ohio nuclear subs cost $2 billion a piece and Navy will be happy if replacement is not 4 times as expensive

The next generation Columbia nuclear submarine program was giving a $8-billion affordability cap, and the program was sitting at about $7.3 billion for the average procurement unit cost (APUC) across all 12 planned submarines.

They have reduced cost by $80 million per hull, to bring APUC down to $7.21 billion.

The “stretch goal” is to get costs below $7 billion per submarine.

The Columbia Submarine replaces the Ohio submarines which cost $2 billion a piece.

The US Navy has a total of 18 Ohio-class submarines which consist of 14 ballistic missile submarines (SSBNs), and four cruise missile submarines (SSGNs). The SSBN submarines are also known as “Trident” submarines, and provide the sea-based leg of the U.S. nuclear triad.

The first of the current Ohio SSBNs are expected to be retired by 2029. It was originally expected that the replacements would be $4 billion per unit compared to Ohio’s $2 billion. Now they are congratulating themselves if they can keep the doubled cost from doubling again.

Although still evolving, the following are some of the ship characteristics for the SSBN(X) design:
* Expected 42-year service life (it is planned that each submarine will carry out 124 deterrent patrols during its service life)
* Life-of-the-ship nuclear fuel core that is sufficient to power the ship for its entire expected service life, unlike the Ohio-class submarines, which require a mid-life nuclear refueling
* Missile launch tubes that are the same size as those of the Ohio class, with a diameter of 87 inches (2,200 mm) and a length sufficient to accommodate a D-5 Trident II missile
* Ship beam at least as great as the 42-foot (13 m) beam of the Ohio-class submarines
* 16 missile launch tubes instead of 24 missile launch tubes on Ohio-class submarines.
* Although the SSBN(X) is to have fewer launch tubes than the Ohio-class submarine, SSBN(X) is expected to have a submerged displacement about the same as that of Ohio-class submarines

  1. So 8x the price, 66% of the payload, and the only improvement is they don’t need refueling. Ripoff I think I will go buy some General Dynamics stock then the ripoff won’t annoy me so much. Lets hope we never have to face an adversary with a semi-honest MIC.

  2. Great when will they all be ready? I like the best, most powerful ability, and all the extra’s. Park anywhere, anytime, all the time. Simple, expensive as are many of my weapons on a personal level. A killer pure and simple!

    • Umm, why? You think an SSBN would have made a difference in the Korean conflict by giving the USA an offshore nuclear capability?
