A large, long range offensve missile defended against by using a shorter range similar weapon?

Why not? What would the technical difficulties be?
Some of the big technical challenges are:

1. Data Fusion - Detection, Classification, Localization (DCL).
2. Salvo on Salvo
3. Acoustic performance (array) of the defensive hard-kill unit in the wake (very noisy).
4. Sizing of the defensive-weapon (array performance, versus weapon size, versus power (propulsion) requirements
5. Fratricide - how do you kill an inbound weapon, potentially in the middle of a battlegroup without putting your forces at risk.
6. Weapon and fire-control backfit on existing platforms.
7. CEP consistency and reliability
8. Many others - this is the surface combatant list. This is and then some for a submarine-launched version.


Do a Search for "anti-torpedo torpedo" and PSU/ARL.
