The US Military is popping its AH-64 Apache assault helicopter right into a drone hunter due to a brand new 30-mm spherical for its M230 chain-gun that may take out Unmanned Plane Programs (UAS) utilizing a proximity fuse that unleashes a blast of high-velocity shrapnel.
Serving with the US Military and others since 1986, the Boeing Apache AH-64 made its title as a tank-killing ground-attack helicopter infamous for its potential to penetrate enemy territory utilizing terrain for canopy, hover in wait, after which pop as much as destroy its goal with out warning.
Nonetheless, the one factor it is by no means been recognized for is air-to-air fight – a lot much less as an anti-drone platform. That may be like utilizing a howitzer to hunt pigeons. It is theoretically doable, however I would not set the desk for pigeon pie simply but.
Sadly, with drone warfare evolving by leaps and bounds, that is just about what the US Military’s Counter-Small Unmanned Plane Programs (C-sUAS) technique needs the Apache to do.
Hunt drones, not make pigeon pie.

To realize this, the Military has seemed again eight many years to the Second World Warfare. Through the battle, bombers posed a serious strategic risk, so methods of taking pictures them down have been filling the drawing boards. The largest drawback was methods to destroy enemy plane with the primitive anti-aircraft weapons of the day. Direct hits have been usually a matter of luck, and time-delay fuses solely made certain the shells detonated at a given altitude – neither of which was passable.
In 1939, Britain’s Telecommunications Analysis Institution (TRE) got here up with the idea of turning anti-aircraft shells into tiny radar units. With built-in circuitry, they may transmit radio waves. When the shell got here close to an plane, this might distort the waves and detonate the shell. Put merely, the shell did not have to hit the plane, simply get within the proximity of it. Therefore the title, proximity fuse.
The idea was sound, however wartime Britain did not have the capability to excellent the weapon or mass produce it. So the key was shared with america in trade for manufacturing energy. Underneath situations of utmost secrecy, the Johns Hopkins College Utilized Physics Laboratory (APL) in Silver Spring, Maryland miniaturized the fuse to slot in a 5-inch (13-cm) shell, hardened it to face up to 20,000 g and the centrifugal pressure of 25,000 rpm, and integrated a battery that would not activate till firing to forestall leakage or failure.
The proximity fuse grew to become one of many key wartime applied sciences, alongside radar, the atomic bomb, the Leigh mild, and the programmable pc, in serving to the Allies win the conflict. Right this moment, it is being referred to as into service once more within the type of the XM1225 Aviation Proximity Explosive (APEX) chain-gun spherical to counter the rising drone risk.

Initially developed for ground-based platforms, the ammunition, with its super-miniaturized proximity fuse, works on the identical precept as its predecessors, utilizing radio alerts to detect its goal’s proximity earlier than detonating and spraying it with a damaging cloud of metal and tungsten-alloy shrapnel.
In accordance with the Military, the XM1225 spherical has been completely examined for security and is absolutely appropriate with each the Apache’s primary gun and its fireplace management software program, in addition to the pilot’s Helmet Show and Sight System (HDSS), for the required accuracy. The spherical is rated towards “soft-skinned” targets, together with Group 1 and Group 2 UAS, uncovered personnel, and small maritime craft, and is orders of magnitude cheaper than the Apache’s different primary aerial weapon, the AGM-114 Hellfire missile. As well as, because the helicopter can carry as much as 1,200 30-mm rounds, the chance of kill per burst may be very excessive, as was demonstrated by live-fire workouts on the Yuma Proving Floor in Arizona in December 2025.
“The XM1225’s proximity fuse has the potential to extend smooth skinned floor and aerial goal vulnerability, offering the Assault neighborhood a further functionality as long as these targets are vulnerable to detection, classification, and monitoring,” mentioned Main Vincent Franchino, take a look at pilot and Assault Division chief at Redstone Check Middle.
