Yes both SNA and SNFO, and I pulled the numbers straight from previous AVT community health briefs. Specifically for YG23 they want to wing 960-something combined. But, I have seen that fluctuate between 950-1100 for previous year groups. In fact CNATRA reports they wing 1100 a year on their website. The ratio is in the ballpark of just under 25% of those being SNFO.
Accession wise, they accept typically 1300 a year across all sources to account for the pipeline attrition rate. OCS typically gets in the realm of 400 plus or minus 50 combined a FY for accession. USNA gets around 280, ROTC just shy of that, and there are typically around 20 from the merchant marine academies. That 400 number I pulled from the accession requirements memos since the former number is the winging requirement. The 67 number is taken directly from the last results memo, im assuming most of the YG-23 accessions are being supplied with PROREC-Ys from the 2021 boards which would account for the low PRORECs in the October board.
