I don’t think the interceptor is expected to survive a successful interception. In the case of a miss, it will be reusable tho, unlike other defense munitions. If any parts of either drone survive, they’ll fall in defender controlled territory, and be available to be fed back into the drone manufacture supply chain.
The mesh increases the ‘hit box’ of the interceptor. It’s conductive, so it is more likely to trigger the kamikaze than a normal in-air collision.
