A while back I saw someone say that the F35B was designed so that the forward lift fan could be turned into a generator to provide power for future directed energy weapons, like a laser weapon or something along those lines.  Is that BS?

If you yanked the fan, you'd have room for a sizeable generator, driven by the original gear box.

OTOH, it would probably weigh quite a bit more than the original fan...

Taking a B model and pulling its fan makes it rather worthless.  But as I understand the A and C model engine configurations have the PTO capability when the technology catches up.

The USAF does not share your opinion and has spent a LOT of money to research putting them on the F35 as an aerial CIWS to shoot down incoming missiles.

I think Boeing got the contract, but I could be wrong.

Lots of potential has been demonstrated in the are of ant-projectile/anti-missile use for DE weapons.

They can already track and detonate artillery rounds in flight, how long before they miniaturize it enough to allow individual Soldiers to where active protective gear that would disable or destroy incoming bullets?

Who needs plate armor when your helmet shoots down every round fired at you?

I think we're very close to this, if we aren't testing already.

Given how effective the fan is at VTOL, I'd say a generator replacement would run an overhead projector.

F35 project was derated to STOVL years ago, and even then it's not meant to be used routinely or it wears out parts.

They'd be better served installing a motor to help drive the turbine engine for better fuel economy

I'm not sure how strong they can make a laser using a generator small enough to fit in a fighter jet. But if they can power it, it can work. Building a laser strong enough to knock down a missile or aircraft from hundreds of miles away is simple. Putting it on a platform that can track and keep the laser on a moving target from hundreds of miles is harder, but still very doable. The hard part is creating a power source that's small enough and light enough to be practical while still providing enough power.

It's pretty easy for a non-mobile ground-based laser. For something you want to drive around, or especially to fly around, it's a bit harder.

When the tech improves to the point that they can intercept ballistic shells and hypersonic missiles you may change your tune.

The tech just isn't quite there yet.

The volume of space required to store energy seems to be a major hangup right now... Of all things that ARF hates, the push for electric cars could end up cracking that nut.

There was also an NKC-135 with a laser test bed on it.  It's sitting at WPAFB last I saw it.

The majority of energy is lost . Highly inefficient.And they can’t shoot into or out of defilade so they are worthless beyond point defense.

The last part will never change. If they were more efficient they may have more utility but very tactical and limited in scope. You aren’t going to vaporize a city or artillery pos with one.

Ehhhh.... I think in 15 or 20 years when aircraft can essentially be made immune to detectable missiles and ground installations can be immune to anything detectable within LOS (IE: mortars, cheap drones) it will be a massive game changer.

Energy storage IS changing with the advent of graphene capacitors and other hi tech solutions. I don't think we should relegate ourselves to dismissing entire fields of technology just because they haven't proven themselves yet.

i just have a hard time imagining something like an abrams sitting still long enough for something like the ABL to take 30 minutes to burn a hole through its armor. They'd have to become much more powerful, and several orders of magnitude more efficient. Either that or our energy generation ability would need to jump 300 years into the future before you could use them very offensively I would think. Maybe if every plane had a mister fusion in the cockpit.

They worked well on ballistic missiles because they follow a predictable path and have mm thick skin and their fuel is incredibly volatile, and artillery shells are packed with tnt.

This ranks up there with the stupid kinetic bombardment threads that get brought up once a year where everyone thinks its a great idea to haul a 300,000 lb tungsten telephone pole into orbit atop a saturn v.  Because its not nuclear.... which means that russia or china wouldn't launch every nuke they have on us if we ever used one against them.

chemical laser size and weigh makes it a dead end for portable weapons systems.  The AF is pouring shit tons of money into laser diode research.  If that follows LED technology's progress over the past decade we're going to see some powerful solid state lasers debuted in the next few years.

A 1MW heat ray style laser (IIRC ABL was 1-3MW) is enough to melt through the roof armor in less than a minute - comparable to AGTM or bomb flight time. No vehicle is going to "dodge" modern adaptive optics.

Compared to fiber lasers, the ABL chemical laser was a Rube Goldberg contraption. It's like ancient one-pixel and spinning rotor wheel missile seekers vs an imaging array.

Energy is quickly lost through atmosphere (absorption, reflection, beam waste, inverse square law)....

Until they figure out a way around that, directed energy weapons on relatively low flying aircraft are stupid.

Laser divergence, distortion and power density is a fairly complicated subject. The inverse square law isn't really the defining problem.

The inverse square law is much more applicable to unfocused energy releases, like bombs, nukes, stars, non-directional antennas.
