You mean prior to the milvax mandate? IIRC the Navy is about 98% fully vaxxed with a FULLY UNcertified vaccine. Weird huh? And remember, they redefined vaccine to fit the lack of prevention of this shamdemic. I view that more as a prophylactic and not a preventative.
The USS Theodore Roosevelt in March of 2020. Out of a crew of 4800, one died and (as I recall) 2 others were hospitalized.

An Outbreak of Covid-19 on an Aircraft Carrier
BACKGROUND
An outbreak of coronavirus disease 2019 (Covid-19) occurred on the U.S.S. Theodore Roosevelt, a nuclear-powered aircraft carrier with a crew of 4779 personnel.
METHODS
We obtained clinical and demographic data for all crew members, including results of testing by real-time reverse-transcriptase polymerase chain reaction (rRT-PCR). All crew members were followed up for a minimum of 10 weeks, regardless of test results or the absence of symptoms.
RESULTS
The crew was predominantly young (mean age, 27 years) and was in general good health, meeting U.S. Navy standards for sea duty. Over the course of the outbreak, 1271 crew members (26.6% of the crew) tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection by rRT-PCR testing, and more than 1000 infections were identified within 5 weeks after the first laboratory-confirmed infection. An additional 60 crew members had suspected Covid-19 (i.e., illness that met Council of State and Territorial Epidemiologists clinical criteria for Covid-19 without a positive test result). Among the crew members with laboratory-confirmed infection, 76.9% (978 of 1271) had no symptoms at the time that they tested positive and 55.0% had symptoms develop at any time during the clinical course. Among the 1331 crew members with suspected or confirmed Covid-19, 23 (1.7%) were hospitalized, 4 (0.3%) received intensive care, and 1 died. Crew members who worked in confined spaces appeared more likely to become infected.
CONCLUSIONS
SARS-CoV-2 spread quickly among the crew of the U.S.S. Theodore Roosevelt. Transmission was facilitated by close-quarters conditions and by asymptomatic and presymptomatic infected crew members. Nearly half of those who tested positive for the virus never had symptoms.
The LCS monohull ships have such small crews (75 max) that routine maintenance work is handled by contractors during port calls. The medical staff on board may have reverted to WWII submarine levels - a Pharmacist's Mate with keys to the medicine cabinet.
