Question to the Ministry of Defence:

To ask His Majesty's Government whether the equipment spend planned for the army over the next five years is the largest of all the services.

Equipment spend forecasts are published in the annual Defence Equipment Plan and the supplementary data tables published alongside show the planned yearly spend for each Front-Line Command. Some equipment budgets are held outside the Front-Line Commands. These include Strategic Programmes (including Complex Weapons and the Global Combat Air Programme) and the Defence Nuclear Organisation. Army Command does not have the largest spend over the next five years.
