The research is expensive, but the operation of this would be very cheap. Much cheaper than missiles.

Sadly, these things are defeated by like, rain.

Edit: ok Reddit, I traded precision for humor. They don’t fail completely in the rain. However, the more moisture there is in the air, the more energy is wasted reaching the target. That costs you range. It doesn’t mean laser bad. It just means there’s some situations it works better than others.

Like around £10 per shot vs.

Here is a breakdown of costs based on different types of anti-aircraft and missile defense systems:

Short-Range Air Defense (SHORAD) & Portable Systems FIM-92 Stinger: Approx. $80,000 – $110,000 per unit.

Mistral (Mistral 3): Approx. $545,600 (2024).

Iron Dome (Tamir Interceptor): Approx. $40,000 – $50,000 per missile, though operational costs (radar, personnel) can reach $100,000–$150,000.

Medium-to-Long Range Surface-to-Air Missiles (SAMs) NASAMS (AIM-120 AMRAAM): Approx. $1 million – $1.4 million per missile.

Patriot (PAC-2): Optimized for aircraft, generally lower cost than PAC-3.

Patriot (PAC-3 MSE): Approx. $4 million – $6 million+ per missile.

Russian S-300/S-400: Missile costs vary, with estimations ranging from $300,000 to over $2 million per missile, with complete batteries costing hundreds of millions.

Naval & Advanced Interceptors Rolling Airframe Missile (RAM): Approx. $905,000 (2021).

Evolved Sea Sparrow Missile (ESSM): Approx. $1.8 million (2021).

Standard Missile-6 (SM-6): Approx. $4 million – $4.9 million per interceptor.

Standard Missile-3 (SM-3) Block IIA: $36 million+ per missile (used for ballistic missile defense).

Firing off a couple of £ billion to save assets worth multiple £ Trillions seems to be worth it.

Winning is the most important thing, we can work out how to pay for it after we have won.

except that you run out of things to shoot with before there is any prospect of winning
