The RAF will equip its Chinook helicopters and A400M transport aircraft with firefighting equipment from 2027, PM Burnham The Chinook fleet, which dates back to 1981, has been reduced from 51 to 45 helicopters. Another 29 are due to be retired by 2030, with only 14 replacements on order, reducing the fleet to 30. The A400M fleet has 22 aircraft but only 10 are mission capable on average. The plan is to increase this to 13 by 2027.
