Retirement? The F-7NI isn’t Going No Where.

For those who have been looking forward to the retirement of Nigeria’s fleet of the Chengdu F-7i Airguard fighter, the recent long-term strategic aquisition plan of the NAF downplayed the potential retirement of the F-7Ni interceptor. The NAF is hellbent of maintaining the F-7Ni tiny fleet through the 2020s. In 2016 there had been speculations that the Air Force was considering replacing its F-7Ni fighters with the JF-17 Thunder multi-role fighter, all though the Air Force would retain its inventory of the F-7Ni.

The $500 million Super Tucano deal for 12 aircrafts ensured the supersonic F-7N will remain Nigeria’s fastest and most potent aircraft, able to carry a heavier weapons payload than any other aircraft in NAF inventory, and for good reasons. In an increasingly high-end threat environment, light and subsonic platforms like the Super Tucano and Alpha jet will not prove as effective as the faster, better armed and more agile F-7N.

For some bizzare reason, the NAF had made its buy rate of 3 combat capable aircraft a year a priority, and will be loath to retire the F-7N unless it has sufficient numbers of new strike platforms.

So since we are stuck with the F-7N we can as well access the capabilities of the only aircraft capable of carrying out air-to-air missions.

Due to its speed and agility, the F-7N is hailed as the poor mans F-16 fighter.

SPEED

The F-7N has a top speed of Mach 2.0 (2,200 km/h). That’s twice the speed of sound.

COMBAT RADIUS / SERVICE CEILING

ARMAMENT

The F-7N is armed with two 30mm cannons, which can fire munitions at the rate of 60 rounds a minute. The aircraft has five hardpoints, four of which are located under the two wings and one beneath the centreline fuselage section. It can carry a payload of up to 2,000kg. The F-7 is fitted with PL-2, PL-5, PL-7, PL-8, PL-9, Magic R.550 and AIM-9 air-to-air missiles (AAM), unguided bombs weighing 50kg to 500kg, a 55mm rocket pod and a 90mm rocket pod.
