The CASA/IPTN CN-235 is also know as "Transallito" in the french air force. This may be the cause of the mistake.
The USCG flies a SAR version as the HC-144A Ocean Sentry but they're now getting the ex-USAF C-27J, so no more HC-144 apart from the 18 they already have.
The fuselage looks good, Papermate!
