What if enemies just start adding mirrors to their planes, drones, etc?
Grab some popcorn and search YouTube for “mirror vs solar death ray.”
Spoiler: magnifying glass plus sunlight obliterate mirror within seconds.
Yes, a small, stationery, “Walmart mirror” would be destroyed easily. Probably without using a death ray.
But military grade glass and cooling (i.e. heatsink) can do wonders.
I’m sure some creative anti-laser technology exists, or will exist, if these laser weapons become more common.
Even infrared reflecting paint + additional cooling might be an option.
Keep in ming that the “target” could have a weapon like this to fire back… No one wins.
You can build lasers that can change thier wavelength (such as an electron wiggler). With a wide enough bandwidth most materials won’t be reflective at some frequency. It’s easy to find this frequency by sweeping the vehicle and detecting reflections. This could be done prior to destruction levels of laser power.
This technology is for use against small and cheap drones. If you fire costly missiles at a 2k drone. The people sending the 2k drones will eventually win out as the defending country can no longer economically support the war. These laser weapons bring the cost down to pounds not 10/100s thousands of pounds per missile. As the target is small drones their ability to carry large deflectors with cooling is limited (payload and range will be diminished).
These small drones couldn’t carry such a weapon. The best they could manage is a one shoot retro reflector. This is a mirror that reflect in the same direction as the source light. Most would burn out in a very short time with this type of weapon.
The instantaneous power would be hard for many aircraft to generate. So this type of systems would be limited to ground based, large ships and possibly well configured jet engines aircraft.
I could be wrong, but I don’t suspect that a laser powerful enough to physically destroy stuff at a distance is going to be meaningfully stopped by regular mirrors, because mirrors don’t reflect all the light pointed at them, and as soon as the mirror gets damaged enough to not properly reflect light in the spot the beam hits, it might as well not be there anyway.
A good mirror reflects more than 99% of incident light, effectively increasing the amount of power the laser needs to destroy the target by a factor of 100.
This isn’t the real concern, however. Fog, dust, clouds, and rain are quite common on the damp and dusty sphere we live on, and they would all strongly attenuate the beam power and greatly reduce the effective range.
You’re not wrong, but at that power level anything longer than a short pulse is going to vaporize the stuff in the way.
They probably take that into consideration and pulse the lazer before giving a more consistent shot.
Clearing out the path before shooting the shot.
Maybe they have a ring around the primary shot as well. Vaporizing the stuff that could get in the way of the primary attack.
These people are smart. It’s easier to assume they’ve taken that into consideration
But is this the same type of light? We’re talking about pure heat damage, how do mirrors reflect heat?
Well I’m basing this off what I’ve seen the Chinese get up to, they have these mounted on trucks so if there is some kind of effective counter like super smoke, idk, inclement weather conditions (lmao), they just don’t roll it out.
Also if these ever get mounted on fighter jets it might be wise to make them part of the automated drone fleets that are gonna be flying in locked formation like Blue Angels. Just don’t send out the laser drones unless necessary idk.
I’m just speculating. You’re stuck buying our shitty F-35s or whatever lol
It’s one of the most financialized and ineffective projects in the entire US military, and that’s really saying something. It’s billed as a hypothetical way for our close allies to use nukes, We would use ICBMs in real nuclear warfare which everyone knows is being stashed actoss Europe and Israel not-so-secretly the F35 shit is LARPing, but anyways conveniently nobody really plans on it since it would result in us getting property damage lol.
Anyways that’s a red herring the real issues is the expense and the production of the parts for it + the amount of time it has to spend being babied by mechanics!
That shit is so unreliable even when it’s not damn near killing the pilots with shitty ejects or weird landings, you want to see a video? It’s Fed up. Guy’s head clearly gets SMASHED against the Fing plane.
It’s way less reliable based on inclement weather than these prototype direct energy weapons.
We have effective weapons programs I don’t feel the need to talk about F35 when it’s so well covered. I can get you democrat, republican, bloodless investor, or communist takes on it
With lasers this powerful weather would be turned to steam, it’s going to clear its path eventually.
Well the power limitations and cooling issues that were previously considered to be insurmountable have been, so you may be right. I guess the question is can it effectively dispatch missiles headed to jets.
Taking out drones with a tank mounted direct energy weapon seems very feasible or having other shit around that can do that
This is going to be a weirdly lit world war.
This is the best summary I could come up with:
The Ministry of Defence (MoD) has said latest trial of the DragonFire system, which typically costs less than £10 a shot, marks a “major step in bringing this technology into service”.
It is hoped the weapon could reduce the UK Armed Forces’ reliance on high-cost ammunition, with the cost of firing the laser for 10 seconds equivalent to using a regular heater for an hour.
Defence Secretary, Grant Shapps said: "This type of cutting-edge weaponry has the potential to revolutionise the battlespace by reducing the reliance on expensive ammunition, while also lowering the risk of collateral damage.
“Investments with industry partners in advanced technologies like DragonFire are crucial in a highly contested world, helping us maintain the battle-winning edge and keep the nation safe.”
Shimon Fhima, director of strategic programmes at the MoD, said: "The DragonFire trials at the Hebrides demonstrated that our world-leading technology can track and engage high-end effects at range.
The development of DragonFire is being led by the Defence Science and Technology Laboratory (Dstl), on behalf of the MoD, working with its industry partners MBDA, Leonardo and QinetiQ.

Have they solved the issues with particles in the air like dust or clouds? Or is it just a good weather defense?
DragonFire was able to destroy incoming drones from several positions miles away, The Times has reported.
Sounds like it. A laser that can cut through metal and plastic at those distances is going to vaporise anything else that gets in its way. Normally you’d have an issue with the surface of the target ablating and vaporising into a dense cloud that does a much better job of stopping photons than the atmosphere (see some Styropyro videos for examples of this in action), but it sounds like it’s strong enough to punch through that as well to finish the job. And quickly enough that it takes out an aerial target, which typically have to move pretty fast to stay airborne. There’s power behind that beam.
