The current USS Boxer (LHD-4) is a member of the Wasp-class of Multipurpose Amphibious Assault Ships. It is not to be confused with the older Boxer, LPH-4 which was a modified Essex carrier and designated as an Amphibious Assault Helicopter Carrier. The current Boxer has an enclosed square bow, the older Boxer has an open square bow. Let me throw another amphib class into the mix -- the LHA Tarawa-class has a slightly rounded bow (more on that later). LHA, LHD, LPH -- confusing isn't it!
The NAVSOURCE Amphib Index may help you sort some of this stuff out.

There are no major gripes against the kit.
There are no dedicated PE sets for a LHD Boxer. DML/Dragon made a USMC Amphib Assault Group which includes some LCACs, Cobras, and SeaKnights (IIRC). It was to accompany the DML/Dragon Tarawa-class LHA (sold as the Saipan). In addition Flagship Models makes a PE set for the Tarawa-class. This set will get you most of the way.

There may be some fit with the deck edge netting, but the railings will cut to fit.
