One of the options for converting surface ships into missile carriers is equipping them with unified quadruple Mk143.
These PU are designed to store and launch Tomahawk and Harpoon missiles. In this case, one PU can accommodate four Tomahawk or Harpoon CRs or two missiles of each type. Prior to their launch, the PU is hydraulically installed at an angle of 35° from the deck. The armored hood protects the missiles from fragments and mechanical damage, as well as personnel in the event of accidental (emergency) triggering of the booster.
