The Harpoon is a mission-kill vice platform-kill weapon. You may not be able to continue your mission after getting hit but you won't be swimming.
FWIW - I was qualified to operate both the Harpoon Attack Console (an enlisted job) AND direct the mode and method of attack (usually the Tactical Action Officer or the CO).
I certainly hope they have streamlined the process in the last 35 years.
