What is one of the first steps in salvaging an LCAC that is stuck?

One of the first steps in salvaging a Landing Craft Air Cushion (LCAC) that is stuck is to put the LCAC in off cushion. This action is essential as it allows the craft to settle onto the solid ground rather than remaining on its air cushion, which can complicate the salvage operation. By transitioning to off cushion, it helps to increase stability and reduces the pressure on the air cushion that might be causing the vessel to remain stuck. This adjustment often aids in assessing the situation under more stable conditions and can also facilitate additional recovery efforts, such as connecting the tow wire or using the dozer blade effectively.

In the context of the other options, connecting the tow wire generally comes after assessing and stabilizing the craft, while raising the dozer blade is a step that may be necessary once the LCAC is in a more stable position but is not the initial action taken. Starting the engine of the LCAC might not be effective if the craft is stuck; the engine's functions may not be sufficient to free it without first managing the air cushion state.
