Death Spiral, JSF Edition

It appears that the UK's order of JSF's may be reduced by as much as 50% because of cost and schedule issues:

The Ministry of Defence may be forced to halve its order for the Joint Strike Fighter (JSF) at the next Strategic Defence Review, according to a report in the Guardian.

The UK had ordered 140 of the aircraft for use by the RAF and on the Royal Navy's proposed new carriers, but the newspaper reports that "a consensus has emerged" that the number of fighters ordered is unsustainable. Delays and cost increases on the JSF programme are said to mean the MoD could be looking to order just 70 of the fighters.

Harrier and Tornado squadrons may also suffer further cuts, the report says, identifying a "huge shift" in spending that is being considered for the Strategic Defence Review following the next general election.

It's really not surprising.

Given today's fiscal environment, and the enormous cost of the JSF, it comes down to a choice of between buying the JSF for a military that lacks the resources to do anything with them, or cutting back and allowing the funds to go to things like ground forces.
