How must submarines launch their Vertical Launch System (VLS) Tomahawks?

Submarines must launch their Vertical Launch System (VLS) Tomahawks while submerged to avoid damage to the system. This method allows them to maintain stealth and ensures that the launch can occur without exposing the submarine to enemy detection, which could happen if it were to surface. Launching from a submerged position also protects the integrity of the VLS system, as launching from the surface could risk damaging the components due to the force of water pressure and potential wave action.

This option emphasizes the tactical advantage of maintaining a low profile in naval operations, leveraging the submarine's ability to operate beneath the surface effectively while still delivering powerful strike capabilities. The other answers suggest operational scenarios that could compromise the submarine's safety or effectiveness.
