Prior to 1977, AA to AL calls were Army, N calls were Navy or Coast Guard.

In 1976 a Notice of Proposed Rule Making was issued by FCC just after the
USCG dropped the assignment of N#AA to N#ZZ callsigns to USCG auxiliary
radio stations, would be thereafter be available for assignment to the
amateur radio service.

Merchant Marine ships were only issued W or K callsigns. Large ships with
radiotelegraphy were issued four letter callsigns. Private  coast  stations
were issued three letter callsigns according the the above information, one
strange exception was RCA's Port Arthur Texas Radio, WPA but since it was
assigned when Texas was in the W callsign area, it makes sense. Private
land stations used for ground to air communications were issued four letter
callsigns like WEAL Eastern Airlines New York station.

Private aircraft were issued five letter callsigns like KHAAQ the callsign
of Amelia Earhart's Lockheed Electra aircraft.

U.S. Navy and U.S. Coast Guard ships were issued four letter callsigns
starting with N, U.S. Navy and U.S. Coast Guard land stations were issued
three letter callsigns starting with N, such as NAA, NSS, NPN, NPO, NMF,
NMA, NOJ.

U.S. Army Corps of Engineers ships were issued four letter callsigns
starting with AE, U.S. Army land stations were issued three letter
callsigns starting with W or in the AA to AL series as example AIR and WAR
in Washington, D.C.  ABM was used by Army to send Notices to Mariners in
the Pacific in Kwajalein.

I hope that clarifies the focus of the article.
