UCAVs With Cannon?

Tue Jun 17, 2008 5:34 am

Are there any planned UCAVs that would possess cannon? While the era of gunfighting seems to be over, cannon allow fighters to possess cheap ground-attack capability, which is why even the latest (Gen 4.5 and Gen 5) fighters have an internal cannon (except the F-35B and F-35C, where it is podded.)

I am specifically asking this in the context of fixed-wing UCAVs, though I suppose the question could separately be asked of helicopter-based or tiltrotor UCAVs.

I doubt it, the ammunition and the cannon itself are heavy and take up a fair amount of space, and I'd imagine the recoil would be significant on such a light vehicle. Also UCAVs are designed to be as low observable as possible and I'd have thought that such a vehicle would need to be fairly close to a target to be effective, putting it at risk of being hit by ground fire. Hellfires seem to work fine.

Direct energy weapons will replace rotary cannons soon. Trouble is building a UCAV that can carry one of these weapon systems. It will be like the A-10 I imagine, design the plane around the gun. UCAV with laser beams.  Smile

All well and good, but I'd imagine on a warm day, with all the thermals and heat haze distorting the laser beam, you may end up lightly singeing the entire tank, rather than boring a concentrated laser into the ammunition storage. Cannons will still have a use, but no, I dont see any UCAV with one, it seems to go completely against their mandate.

There is a fix for that particular problem which astronomy have been using for many years on earth bound optical telescopes. Fire a low power laser to clear the path by evening out the column of air. In optical telescopes this has the effect of negating the flicker/twinkle caused by the atmosphere. A similar method is employed on the ABL system being developed for the USAF. The biggest obstable is scaling the system down to fit into a reasonable sized UCAV.
