Fiber optics is already a non-ML solution to jamming (and RF based detection).
- beeflet 2y agoHow does that work? fiber optics are delicate. you mean free-space optics?
- mmcwilliams 2y agoVery long spools are connected to the drone and it is flown by wire until it strikes its target.
- solardev 2y agoLike a TOW missile or early torpedoes? Surprised we still use that method, but I guess it works!
- dilyevsky 2y agoYes the method is nothing new. The novelty is FPV, considerably longer range (15km+) and relatively low cost.

- paywallasinbeer 2y agohere's a video from ukraine showing fiber optic cables all over the ground: https://files.catbox.moe/fx980o.mp4 https://files.catbox.moe/fx980o.mp4 maybe someone will find this interesting like I did.

- relaxing 2y agofree-space optics are sensitive to atmospheric attenuation and los. you mean fiber optics and be careful not to fly in a way that exceeds the bend radius.
- mattlondon 2y agoCurrently in Ukraine both sides are apparently using spools of fibre on their drones due to the RF environment. ISTR reading that they're able to carry several KM of fibre each. Delicate doesn't really matter - these are kamikaze drones carrying shaped-charge explosives or anti-personnel grenades, often taking out individual soldiers one by one (as well as tanks etc). Seems wasteful but potentially the near to midterm future of warfare?
- jcgrillo 2y agoNot wasteful at all when compared to the cost of "conventional" munitions.
- bronco21016 2y agoThis is incredible. Especially the link below to buy the system. I see it unspools at the drone to prevent tangling. How you prevent being traced if some of the enemy’s survivors follow the thread?
- bglazer 2y agoHow do you prevent being traced? I believe the answer is you shoot at them with automatic weapons.
- red-iron-pine 2y agoincredibly thin, hard to find fiber optic, laying on the ground in a live combat zone -- essentially a non-issue it's the same idea as SACLOS anti-tank missiles that are "wire guided". if someone is shooting those at you, you have way bigger things to worry about than tracing cables -- you're in a killzone, so try not to die.
- bluGill 2y agowhy follow the cable - they already know what direcion you are in. By the time they can follow the cable several km back you have already moved elsewhere. and of course you never are alone so someone else is watching for them to come and will shoot them just like any other attacker coming your way. attackers have it easier as they can stick to cover while following the cable means they are in the open in places near your line.

- red-iron-pine 2y agovery well, and functions similar to SACLOS missiles. arguably the same basic idea, just with more maneuverable payloads. crystal clear recordings out there of said drones if you're willing to stomach r/combatfootage or similar
