Honestly, I fail to see this missile's utility
How Will you even guide it at that Distance, because ASW Helicopters Don't Have that kind of Range and bigger ASW platforms like P8i carry their own torpedo in good enough numbers and don't exactly need assistance from the Shore.
For Reference P8i have 11 hardpoints
In My Opinion a SMART type missile based on Prahaar would have been much better because It could
1. Can be Launched from a Ship
2. Cover A more reasonable and modest Distance of 150km which can be surveyed by Ship based Assets
3. Be of actual use because ASW helicopters carry only 2 Torpedoes and the helicopter can request help from the warship after expending it's own salvo in the form of these Missiles
