IAFM - Ship Types - Frigate Platform Dock (FPD-150)
Introduction The Frigate Platform Dock (FPD-150) is the most flexible ship in the IAFM. It came about when I was mulling over how to provide enough escorts for SAGCOMs and CVCOMs, while still supporting forward deployed Marine forces. The existing US Navy force model splits amphibious vessels (LPD, LSD, LHD/A) and escorts into distinct pools. However you still have to provide escorts for ESGs as well as CVBGs. But if you look at a modern amphibious ship, like the LPD-17, the systems aboard aren't that far off from those on a frigate. It has an air defense radar, short-range SAM systems and C4ISR. So my thought was, why not smash together the capabilities of a guided-missile frigate and a modest-sized LPD and make a self-escorting "Frigate Platform Dock"? This way, every ESG is always self-escorting. Also, an ability to perform strike with VLS-based munitions, and Naval Surface Fire Support (NSFS) with Multiple Launched Rocket System ...
