When submarine-launched SAMs might buy an escape

What does the panel think of IDAS and the wider idea of a submarine-launched surface-to-air missile?

It is best treated as a last-ditch distraction that might open an escape window, not as a dependable submarine air-defence system.

Targeting and access to suitable data are the first difficulties raised for a submarine-launched surface-to-air missile. A full-size weapon also consumes space that could hold a torpedo or strike missile, and firing it reveals that a submarine is nearby. Smaller cold-launched weapons in the sail are considered more plausible for confined waters such as the Baltic or Mediterranean. Their proposed role is a last-ditch attempt to distract an attacker long enough for the submarine to escape. Modern standoff anti-submarine weapons weaken that prospect. A closing correction notes that helicopters carried torpedoes as well as depth charges, so the historical comparison should not imply that they once relied exclusively on depth charges.
