A tethered radar drone as a warship's elevated sensor

Could tethered drones be useful in naval warfare despite electronic warfare concerns?

Yes, particularly as elevated radar platforms, but their extra coverage must be weighed against the risk of revealing the ship's position.

The speakers imagine a tethered drone carrying a radar system above a warship while conventional sensors remain aboard. Elevation would extend the radar horizon and provide part of the perspective normally associated with airborne early warning. The tether offers a physical control and data path in an electronic-warfare environment, but the elevated platform and its emissions can reveal the parent ship. The trade is most attractive in places such as a canal transit where observation is already unavoidable and maximum awareness matters more than concealment.
