Ukraine's F-16 pilots are so short of air-to-air missiles that on some daytime sorties they go up with nothing but the plane's gun. Instead of using effective AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) and the shorter-range AIM-9 Sidewinder, Ukrainian forces are left with the M61A1 Vulcan 20mm rotary cannon, which can pose a grave danger to civilians, the War Zone reports.

Destroying Russian targets with the M61A1 Vulcan 20mm rotary cannon carries risks: the cannon rounds, similar to grenades, can strike a fairly wide area when they hit the ground, potentially killing innocent people.

Worse, the AIM missiles the F-16s are rationing are the same ones that arm the NASAMS batteries defending Kyiv, so every jet-fired round competes with ground air defense for the same scarce stock.

A 107th Wing commander using the callsign "Phantom" confirmed the shortage when a journalist asked him directly whether Ukraine was severely short of missiles for its F-16s.

“Yes, that’s true. Any aircraft without weapons is … useless,” Phantom said.

Kyiv wants the missiles, and a way to make them

Stopping as many Russian Geran drones and cruise missiles as possible before they reach Ukrainian cities takes missiles, and Phantom was blunt about what the fleet needs. He called for more air-to-air missiles and for interceptors to reload the US-made ground-based Patriot batteries.

"We require more means of protection, such as Patriot missiles and air-to-air missiles, AIM-9s or AIM-120s to our fleet," he said.

The fix he wants outlasts any single shipment: "At least we need to try to increase the production, or at least to allow Ukraine to localize the production in Ukraine or other European countries."

Until that exists, the arithmetic stays brutal, as every missile fired at a Russian drone or cruise missile is one fewer for the next attack.

A cheaper rocket enters the mix

One weapon Phantom did not mention may ease that math. Ukrainian F-16s now appear to carry the laser-guided 70mm APKWS II rocket.

Built from a standard unguided rocket fitted with a laser-guidance kit, it is far cheaper than an AMRAAM and has already become a primary anti-drone weapon for US jets in the Middle East — a lower-cost way to knock down drones and subsonic cruise missiles without spending a scarce air-to-air missile on each one.
