Estimate of new nuclear missiles to replace Minuteman 3 arsenal increases to $95.8B

WASHINGTON — The Pentagon has raised to $95.8 billion the estimated cost of fielding a new fleet of land-based nuclear missiles to replace the Minuteman 3 arsenal that has operated continuously for 50 years, officials said Monday.

The estimate is up about $10 billion from four years ago.

The weapons, known as intercontinental ballistic missiles, or ICBMs, are intended as part of a near-total replacement of the American nuclear force over the next few decades at a total cost of more than $1.2 trillion.

Some, including former Defense Secretary William J. Perry, argue that U.S. national security can be ensured without ICBMs, but the Pentagon says they are vital to deterring war. The Trump administration affirmed its commitment to fielding a new generation of ICBMs in a 2018 review of nuclear policy.

“The ICBM force is highly survivable against any but a large-scale nuclear attack,” the review concluded. “To destroy U.S. ICBMs on the ground, an adversary would need to launch a precisely coordinated attack with hundreds of high-yield and accurate warheads. This is an insurmountable challenge for any potential adversary today, with the exception of Russia.”

The current fleet of 400 deployed Minuteman missiles, each armed with a single nuclear warhead, is based in underground silos in Montana, North Dakota, Colorado, Wyoming and Nebraska. Their numbers are governed in part by the 2010 New START treaty with Russia, which is due to expire in February. Russia wants to extend the treaty but the Trump administration has set conditions not accepted by Moscow.

The U.S. also is building a new fleet of ballistic missile submarines to replace the current Ohio-class strategic subs; a new long-range nuclear-capable bomber to replace the B-2 stealth aircraft; a next-generation air-launched nuclear cruise missile; and a new nuclear command and communications system. It also is working on updated warheads, including an ICBM warhead replacement for an estimated $14.8 billion

The nuclear modernization program was launched by the Obama administration and has been continued by President Donald Trump. Democrat Joe Biden has said that if elected in November he would consider finding ways to scale back the program.

The Pentagon's $95.8 billion cost estimate for the Minuteman replacement was first reported by Bloomberg News. The Pentagon provided the estimate to Congress last month but had, until Monday, refused to release it publicly.

Last month the Air Force awarded Northrop Grumman a $13.3 billion contract for engineering and manufacturing development of the new missiles. The total “lifecycle” cost, including operating and sustaining the missiles over their expected lifetime into the 2070s, is set at $263.9 billion.

    Main contractor Damen and more than a hundred companies contribute to combat support ship

    February 19, 2020 - With the contract signing for construction for the new supply ship HNLMS Den Helder, more than a hundred, mainly Dutch companies receive work. The contract was signed today in Den Helder by the Director of Defence Material Organization (DMO), Vice Admiral Arie Jan de Waard and Arnout Damen, the new CEO of the family business Damen Shipyards Group. Damen Schelde Naval Shipbuilding (DSNS) will supervise the project, together with DMO, as the main contractor. Damen will not do this alone; more than a hundred companies from the Dutch naval construction sector are involved in this ship. This means that a large part of the sector will be deployed to participate in this innovative new ship. With HNLMS Den Helder, the maritime supply capacity of the Royal Netherlands Navy will be restored. The ship will operate alongside the Joint Support Ship HNLMS Karel Doorman. This vessel also forms the basis for the design of this Combat Support Ship. The new ship can be used worldwide and can operate under high threat, protected by frigates. In addition, she can be used in the fight against drug trafficking, controlling refugee flows and providing emergency aid. The supply ship, which is almost 200 metres long, will receive a 75-person crew and can also take 75 extra people on board. There is room for several helicopters and around 20 containers. The design explicitly looked at fuel consumption and exhaust emissions. The combination of diesel engines, hull shape and propeller design reduces fuel consumption by around 6 % compared to HNLMS Karel Doorman. The building contract is not contracted out elsewhere in Europe. DMO wishes to keep the knowledge and skills of designing and building naval ships in the Netherlands. The armed forces thus invoked Article 346 of the Treaty on the Functioning of the European Union. It states that Member States may protect essential security interests. This also relates to the production of defence equipment. Completion is scheduled for the second quarter of 2024. A year later, in the second quarter of 2025, the Combat Support Ship must be operable. The size of the total project budget is 375 million euros.
