The title is definitely tongue in cheek. Perhaps the Brits came up with a suitable work around...the stern gate.
But here's a primer on the LHA-6 gate issues (note the reference to the failed operations of the LPH during the 1970's) ...

An aviation-centric amphibious ship is not a new concept. In the late 1950s, the Navy built a class of amphibious assault ships called Landing Platform Helicopters, or LPH. These vessels carried Marines and rotory-wing aircraft. The only way to leave the ship was by air.and this...oh and note...that's the same Robert Work that's now Under Secretary of the Navy...
“That turned out to be largely a failed experiment,” says Work. In operations off the coast of Lebanon in the late 1970s, the ships’ helicopters encountered a significant air threat that resulted in the Marines being transferred to another amphibious ship to go ashore by sea.
“What we learned about the LPH is that we needed a well deck,” says Marine Col. Robert Coates, director of the 1st Marine Expeditionary Force’s training and exercise group.
The aviation-centric design of the LHA replacement — or LHA(R) — also has raised questions about its long term usefulness. Considering that Marines require heavy trucks and armored vehicles once they reach the shore, most of that equipment can only be transported by hovercraft, not by helicopters.
“It’s been a long-running debate, and it’s still not settled,” says Robert Work, a naval analyst with the Center for Strategic and Budgetary Assessments in Washington, D.C. “There are a lot of questions on LHA(R). Will it become the standard, or will it become only a niche capability?”
