Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the cost to the public purse is to sustain a Challenger 2 squadron, based on 14 platforms, for (a) seven days, (b) 28 days, (c) 90 days and (d) six months.

The Department carefully considers the cost of using, deploying and sustaining platforms, including those granted to Ukraine. The costs associated with the specific metrics requested by the right hon. Member would however be subject to many variables and include commercially sensitive information. I am therefore unable to provide an assured figure.
