Trying to make sense of 076 in relation to USN LHA-6/7 "Lightning Carriers" encounters the problem that those ships themselves are rather perplexing, in that it is difficult to imagine any non-specialized USMC/USN requirement that could be addressed with only two ships.
Delving into the history of these vessels, we find that LHA(R) was indeed intended to feature a well-deck as of
. We further find that,
, a well-deck featured in the then-favoured "plug plus" configuration that increased both length (+77ft) and beam (+11ft) over preceding LHD-8. Yet a scant few years later we find that LHA-6 has been laid down with baseline dimensions near identical to LHD-8, increased aviation capacity, and no well deck, to be followed up by additional ships (LHA-8 and beyond) that restore the well deck, presumably at the cost of reduced aviation capacity, returning to something like the baseline provided by LHD-8. A more detailed comparison of LHA(R) "plug plus" and final approved LHA-6 "Flight 0" configurations can be found in
presentation.
How do we account for this series of decisions? The major feature to be explaining is the apparent insistence on increased aviation capacity for LHA-6/7 (envisioned for JSF and MV-22) followed by subsequent reversion to the mean with LHA-8 and beyond. It appears that the more ambitious (and well-deck-including) "plug plus" configuration was likely foreclosed by budget considerations but, when a retreat from that configuration was required, the enhanced aviation capacity was kept at the cost of the well deck. In the absence of a smoking gun that clearly establishes the facts, two narrative pathways present themselves: (1) That this is all part of the general malaise and doctrinal uncertainty of post-Cold War and GWOT-era USN/USMC. See: Zumwalt, LCS, Desert Storm, Donald Rumsfeld, Revolution in Military Affairs, Revolution at Sea, Forward from the Sea, SC21, etc. No doubt this is all implicated, yet a tighter narrative also presents itself:
The years of consideration and approval of LHA-6/7 with enhanced aviation capacity also coincide with years of debate concerning the size of USN's aircraft carrier inventory, as the last of USN's conventional carriers (USS
John F. Kennedy CV-67 and USS
Kitty Hawk CV-63) and the earliest of its nuclear carriers (USS
Enterprise CVN-65) approached the end of their careers. In what is now a familiar dynamic, USN sought to retire elderly ships while Congress sought to maintain numbers, culminating in legislation requiring the Navy to maintain "not less than 12 operational aircraft carriers" (subsequently amended to 11).
2006 CRS report notes that Navy officials specifically pitched the expanded aviation capabilities of LHA(R) as partly compensating for the proposed retirement of USS
John F. Kennedy CV-67.
Hence it is my interpretation that the aviation-centric configuration of LHA-6/7, while a mixed bag from USMC perspective who really wanted "all of the above" (i.e. a well deck as well), was likely sought and approved by USN because it helped to mollify Congress regarding declining carrier numbers and secure approval for the retirement schedule of the aforementioned three carriers. This task having now been accomplished, and carrier numbers more-or-less stabilised at 11, with future retirements more-or-less paired with inductions, LHA-8 returns to the LHD-8 mold, again with a well deck and reduced aviation capacity.
