Shooting down $40k drones with $4mil interceptors is a problem. Hoping at some point this wake up call is heard.

One recent update is that Apache Attack helicopters are being refitted to hunt/kill these types of drones, but the newest Iranian models are flying 300+ mph which is faster than a single rotor helicopter can fly (the leading blade of a helicopter starts to break the sound barrier).

US forces have been answering the wake up call for the last few years.

The main weapon that Apache's use to hunt drones are laser guided rockets (APKWS) with a per-shot cost around $30k (https://www.airandspaceforces.com/apkws-base-laser-guided-ro...)

These weapons have been fitted to most US tactical fighters for the counter drone role as well. APKWS is also not a "new" weapon system - it started fielding back to 2012, and was adapted into the counter drone role.

There are other lower cost (compared to legacy systems designed to take on manned aircraft) solutions currently deployed. The US Army has the Coyote, which is in the ~100k range.

Beyond cost of munitions, you have to consider that cheaper systems are going to have less range, and therefore you'll need more launchers, and you can start running up costs that way.

Israel, United States, United Kingdom, China and Russia have HEL high-energy lasers that can shoot down fast drones. Several other countries are working on HEL development. The numbers of operational HEL systems are still very small but growing. I believe that Israel have the most of them in operation today developed primarily by Rafael Advanced Defense Systems. 10kw to 50kw on trucks, 100kw ground based. Range: 7-10km, shorter in fog or rain. Dwell time: 4 to 5 seconds. Cost per shot: $2–$3.50.

Targets: UAVs/drones (including swarms), short-range rockets (Qassam-style), mortars, artillery shells, cruise missiles, and potentially other low/slow-flying threats. It excels against cheap, high-volume threats where kinetic interceptors are uneconomical.

The US is working on a megawatt version that will be mounted on ships to take down full sized aircraft, hyper-sonic weapons and ballistic missiles. Timeline: 2030. Even at 30-50 kW (e.g., the earlier AN/SEQ-3 LaWS on USS Ponce), lasers can target helicopters or manned aircraft to cause crashes by frying sensors or engines. Scaling to hundreds of kW extends range and lethality against faster, larger aircraft.

Surprising there are not more solutions here. We have seen these style of drones for a number of years. I guess it’s a hard problem in general but I also wonder if part of it is simply the historically entrenched defense industry.

The way things are going, no, let's hope the US never wakes up for this problem.
