It sounds poorly thought out by brass that wanted all thing to other brass. A ship requiring that much maintenance with no crew at sea is not reliable in combat. It isn’t a plane that can be easily replaced when it is down. It is a warship.
With the crews forced inside they have no access to sun and fresh air. It is vital to moral on a ship. Submariners are trained and rewarded for months of underwater duty. Sailors on this ship are not.
You won’t find too many complaints about six hours of a hot rack. Any good sailor can grab a nap on light duty but it sounds like this ship is so undermanned sailors are pushed to exhaustion. Exhausted humans make mistakes. If this story is true that is....
The minesweeper instrument on my project got moved to the LCS so they could add another mission to the ship’s capability. But the instrument weighed 1,000 pounds and was helicopter towed by a MH-53. To move it they had to tow it with the much smaller LCS’ MH-60. Towing with the 60 meant the helicopter had to go so slow that if there was a problem they’d drop in the drink before recovery. So, they regularly towed it faster which put them at the edge of their stress level. The pilots regularly guillotined the $150k tow cables and lost the multi-million dollar package thereby requiring a $300k deep dive recovery. So, the political decision to move the mission to a ship it was unsuited for led to the Navy losing a potentially good minesweeping device. Pure politics.
I have to wonder what other mission were moved to the LCS for which it is also unsuited. For example, Hezbollah has Chinese made, Iranian supplied anti-ship missiles it fires from shore. They have hit five Israeli patrol boats resulting in loss of life. The Israeli boats are MUCH smaller and harder to hit.
Also, a single mine would destroy the LCS’s very light hull. I think this is another idea-fart from a planner who spent his career at a desk.
I hate to think what would happen if it was badly damaged by something...like a direct hit. Who would keep it afloat?
