Ex USAF 55-4505, operated for the US Coast Guard from 1960 until 1972 as 4505, then stored at MASDC until acquired by the Pima Air Museum in September 1978. Note that all USCG C-123B Providers are widely quoted as HC-123B, but this is incorrect. They were used for LORAN site checks and other non-SAR duties, and were never equipped for SAR missions. As a result, they did not receive the "H" type prefix, and all official USCG documention consistently refers to them as "C-123B".

This airframe is often mistakenly identified as an SA-16B or HU-16B (long-wing conversion). In reality, it is the only unconverted, standard-wing HU-16A on display in the USA.

One of 13 C-130As converted to ski-equipped C-130D aircraft, for use in the Arctic.

Delivered in 1941 as regular Invader serial 41-39378. Converted to Counter Invader in 1963 by On Mark, and reserialled 64-17653. Stored at MASDC in 1970, transferred to the USAF museum in 1973, and loaned to the Pima County Air Museum in 1974.

Delivered to the US Navy as Bu37257 on 9 Aug 1945. Stored at Litchfield Park, AZ on 30 Jan 1954, then sold as N7255C in 1957 and stored unused at Douglas-Bisbee, AZ. In 1974 its rear fuselage was exchanged with the damaged rear fuselage of N6856C c/n 15-1156. In Dec 1975 the now damaged aircraft was donated to the Pima museum, but remained stored at Douglas-Bisbee until it was trucked to the museum on 30 Mar 1982. There it was stored yet again until restoration finally began in 2003. During that process the aircraft was mistakenly painted as 32757 instead of 37257. As can be seen, the Navy blue has faded considerably over the past 20 years. A repaint would be a good opportunity to also correct the serial.

Former US Army EO-5C, now stored in the restoration yard of the Pima museum. Still has small U.S. Army titles on the nose.

Formerly operated as a US Army EO-5C, this aircraft is now stored in the restoration yard of the Pima museum. Some of its old sensor fittings are still present.

Falsely painted in Marines markings as Bu1061 (the real 1061 was c/n 4344), this rare S-43 has in fact never seen military service. It was delivered in Jan 1937 as NC16934, and it kept that registration (later as N16934) until it hit a floating log on landing on Chignik Bay, AK (not on Tetlin Lake as widely reported) on 1 Jun 1951. Its hull ruptured, aircraft sank, registration cancelled 27 Jun 1951. Wreck salvaged 30 years later by Gary Larkins' and Darryl Greenamyer's Institute of Aeronautical Archaeological Research (Air Pirates) in 1981, and trucked to the Marine Corps Air-Ground Museum at MCAS Quantico, VA. It was loaned to the Pima museum in 1985. Often reported as becoming N326, but this is not correct (N326 was c/n 4342).

This aircraft has been in these white markings for about 30 years (since the first half of the 1990s), and is now in need of a repaint. The serial on the tail has completely faded away on both sides.

Previously painted with a blue trim and fake registration N6000V. Was repainted in its original US Army markings in 2011.
