We just lost two also...One in Dec 2015 and another in March 2106. Several sailors were injured in one of those mishaps.
True, but we are conducting vast numbers of flight hours compared to the fledgling Russian naval aviation.
We have had two in the last year, they have had two in two weeks according to this article. Now they have one carrier versus our eleven carriers and how many sorties have each launched? Our accident rate must be at least one, maybe 2 orders of magnitude less than theirs.
