Depends on what you're defending against. Drones are effective because they're cheap so they can be sent in large numbers to overwhelm air defense even if each individual drone is an easy target.
- nradov 4y agoThe type of cheap drones that can be sent in large numbers lack the range to attack ships unless they're really close.
- littlestymaar 4y ago“Cheap drone” doesn't need to be off the shelf quadcopter drone, fixed-wings custom drones like the Iranian Shahed 126 are still dirt cheap compared to typical anti-ship missiles.
- nradov 4y agoThose lack the sensors needed to detect and track a moving ship. Good sensors are expensive, and consume a lot of power.
- rcme 4y agoA ship isn't exactly a small target. You could probably track it just fine with a satellite and update the target GPS coordinate of the drones manually. An aircraft carrier only moves at 55 km/h maximum.
- nradov 4y agoNope. Ships are very small targets in very large oceans. Have you ever even been on a boat out of sight from land? Reconnaissance satellites will be the first casualties in any future high-end conflict. Modern militaries have to plan around the expectation that their space-based platforms will be unavailable or severely degraded. Radar ocean reconnaissance satellites can detect ships under any weather conditions but they are are large, heavy, expensive, and can provide only intermittent coverage. Smaller satellites with optical or IR sensors can potentially provide more coverage but are less effective at night or with clouds.
- rcme 4y agoApparently China is already tracking U.S. aircraft carriers via satellite: https://www.scmp.com/news/china/science/article/3177079/chinese-smart-satellite-tracks-us-aircraft-carrier-real-time https://www.scmp.com/news/china/science/article/3177079/chin... And sure, you need to wait for a clear day, but that doesn't seem like too big an obstacle. Also, while space-based platforms will be targets, it's unclear how effective counter measures are. Identifying targets is challenging and deploying replacements is worth the cost if you can eliminate a large portion of an adversary's naval power.
- nradov 4y agoThis is nothing new. The USSR was tracking US aircraft carriers via satellite since the 1960's. China is only now catching up. Carriers are certainly vulnerable to an extent, but detecting one with a satellite is only one step in the kill chain. Carrier strike groups already carry some limited anti-satellite weapons that can hit targets in LEO. There is an active arms race underway by the superpowers to boost those capabilities, and also (as you stated) to develop a prompt launch capability to replace satellite attrition losses within hours rather than scheduling launches years in advance.
- iamwil 4y agoApparently, the oceans do a lot of radar scattering that makes it harder to spot ships from the guidance systems of missiles. Not sure what the state of the art is nowadays though.
- littlestymaar 4y agoThat's basically how most Anti-ship missile work: you give them GPS coordinate for the rough location and then the missile uses an active radar homing system for terminal guidance. (You want the missile to keep quiet as long as possible anyway, to avoid being detected and reducing the time the crew has to react to the threat).
- littlestymaar 4y agoBut you don't need one sensor per drone, but one per swarm with the same target (and any kind of data link between members of the swarm). And by the time the swarm is within reach of the protection weapons of the target, it's probably close enough for the fairly basic sensors onboard of every drone to be able to work on its own if the target drone is destroyed (for instance: GNSS up to the last know position of the ship, and then just computer vision at close-range).
- actionfromafar 4y agoSo far. There are many ways to make longrange, fuel efficient flying things.
- nradov 4y agoWhat are those ways? Do they also allow for large sensors and warheads?
- actionfromafar 4y agoJust being the overconfident random internet person with ideas: launch 100 vehicles, slow flying, potentially with gliding capabilities, converging from all directions onto a target at the same time, ditching main wings and piston engine at the last minute, firing a rocket to gain speed, and overwhelm air defence by sheer numbers. Combine low-flying attack profiles with "dive-bomb from above". Large sensors can be mitigated with mesh-networking between vehicles and sensor fusion, maybe different kinds of sensors on different vehicles. Slow-flying means they can carry heavier warheads thanks to more lift and less drag. If slowly circling at high altitude, you also tie up resources keeping track of them. Quantity is its own quality, and all that... this is all without even bringing "AI" into the mix, but if you could, you can give them "goals" instead of targets.
- nradov 4y agoIt is possible in principle to build a loitering cruise missile with those features. It will not be small or cheap, at least not if you want something with the range and endurance to seek out and attack a ship on the open ocean in any weather conditions. Add up the cost and weight for all of those components you listed. As a point of comparison, the latest Block IV Tomahawk missiles already do most of what you described. They cost about $2M each and weigh about 1.5 tons. Only the largest warships can potentially carry 100 such missiles. Russia has used small, cheap cruise missiles like the Iranian Shahed-136 drones with some limited success against Ukraine. In a naval conflict such drones could have some value as harassment weapons against surface vessels operating in the littorals. But those drones are useless against moving ships over the horizon.
- justsomehnguy 4y agoJust take a bigger drone truck to get them there. happy Protoss Carrier noises
- Aeolun 4y agoI’m absolutely in favor of a massive airship spewing hundreds of drones :)
