Would like to point to a nice summary of aviation assets that is available on line from the US Naval Institute (USNI, unfortunately behind the pay wall–see late addition below). It is the work of a friend, Jim Dolbow, who many years ago encouraged me to blog. He now works for the USNI and is responsible for the two latest editions of the Coast Guardsman’s Manual.
Included are aircraft of the Marine Corps, Navy, Coast Guard, U.S. Customs and Border Protection’s (CBP) Air and Marine Operations, and NOAA as of 31 July, 2018
Navy and Marine units list aircraft type, squadron, and base but don’t actually list numbers of aircraft.
Coast Guard aircraft numbers, by type, are listed below, but the article goes on to identify number and type at each CG air station. It also notes there are 160 civilian CG Aux. aircraft.
Coast Guard aviation as of 31 July 2018 consisted of 7 different types of aircraft representing 207 airframes based at 27 different locations, including:
(17) HC-130H Hercules
(9) HC-130J Super Hercules long range surveillance aircraft
(18) HC-144 Ocean Sentry medium range surveillance aircraft
(14) HC-27J Spartan medium range surveillance aircraft
(2) C-37A Gulfstream V
(45) MH-60T Jayhawk medium range recovery helicopter
(102) MH-65D/E Dolphin short range recovery helicopter
I was a bit surprised to find the U.S. Customs and Border Protection’s (CBP) Air and Marine Operations had more aircraft than the Coast Guard, 97 fixed wing and 128 helicopters (vs 60 fixed wing and 147 helos for the CG). Numbers of each type is provided but no information on basing.
NOAA has nine manned fixed wing aircraft, identified by number and type, all operated out of NOAA’s Aircraft Operations Center at Lakeland Linder Regional Airport, FL.
Late addition:
Just realized the USNI post is only available to USNI members (You really should be a member). Hopefully they will forgive me if I copy and paste a good chunk of the CG portion below.

Doesn’t the USCG also share the use of Two “Aerostat” Balloons with the USB&CP Services and also have access to ~8 Lockheed P-3B AEW&C which also does Drug Interdiction missions…
The listing includes 12 CBP Orion P-3s some are AEW aircraft but I’m not sure how many. Don’t know about the Aerostats, but I think the vessel mounted aerostats are gone now.
One of the “Aerostat’s” is located at Corpus Christi, Texas in conjunction with P-3B AEW&C and the other at Aguadilla, Puerto Rico…
So did the “Civil Air Patrol”…
( http://www.maxwell.af.mil/News/Feature/Display/Article/1024853/civil-air-patrol-a-story-of-unique-service-and-selfless-sacrifice/ )
The Coast Guard flew CBP aircraft on the Texas Border in the late 1940s. They were assigned for ATF and Immigration patrols.
Strange the Coast Guard uses “Order of Battle” when Coast Guard Aviation has no military mission.
That may not have been the Coast Guard’s choice of words.
The Coast Guard HAS several military missions. There are 5 military services
Don’t forget Donald Trump’s new Space Force Command
( http://youtu.be/t6CVMGWZ0pc ) …
There are two MH-65’s at AIRSTA Washington in addition to the G-V’s
5th District or 13th District…
Washington DC.
I seem to remember all of our helicopters have been modified to permit “Airborne Use of Force,” but always seems that only the helos from Helicopter Interdiction Tactical Squadron Jacksonville (HITRON) seem to be on ships that go to the Eastern Pacific.
Are any of the other air stations actually prepared to employ Airborne Use of Force?
The “Civil Air Patrol” ! As I recall, the CAP was used as Aerial Coastal Coast Watchers against German and Japanese Submarines in WWII…
Coast Guard auxiliary searched for subs during WWII also.
