21 October 2020 | Much has been made of the decision taken to employ a delta symbol for the new U.S. Space Force (USSF), which operates within the U.S. Air Force (USAF) much as the U.S. Marine Corps’ relates to the U.S. Navy. The symbolism is clearly visible on the USSF seal, ensign, current senior enlisted rank insignia, and in the service’s organizational command structure. Furthermore, recently (21 October 2020) Lieutenant-General Stephen N. Whiting became the commander of the USSF’s Space Operations Command at Peterson Air Force Base, Colorado; the delta is, as one would expect, prominent in the logo. Some pundits are of the opinion that the adopted symbol is inappropriately appropriated from the ‘Star Fleet’ emblem regularly seen in the 1960s television series Star Trek. (Readers are directed to the Space.com article U.S. Space Force says its new seal is not a Starfleet knockoff.) Is this the case and is the ‘delta’ appropriate for USSF adoption?
USSF officials contend (see the Defense.com post Space Force Flag Unveiled at White House) the criticisms are without merit. In fact, USAF connections to outer space and deltas go back to the beginnings of the ‘Space Race’ in the 1950s and early 1960s. By 1953 the positive aspects of delta aerofoils/airfoils were incorporated into various flying machine designs that entered USAF service. The delta aerofoil, which is shaped like a triangle, gets its moniker from the Greek uppercase letter delta (Δ). This design possesses noteworthy advantages for designers of high-speed aerial vehicles.
The National Aeronautics and Space Administration (NASA) Mercury 7 astronauts, who were announced and introduced to the public in 1959, were turbojet fighter or fighter-bomber pilots. During their tenures with NASA piloting delta-winged interceptors helped to maintain necessary and critical piloting skills. The group of delta-equipped jets entering the USAF inventory before and during the decade included the Convair F-102 Delta Dagger , Convair F-106 Delta Dart  interceptor, and Convair B-58 Hustler  supersonic bomber. Notably, the 14 September 1959 issue of Life magazine featured articles about the astronauts and contained photographs of Alan B. Shepherd, a U.S. Navy officer, within a USAF F-102 cockpit after a flight.
The F-102 was barely supersonic, and NASA therefore obtained speedier USAF F-106s and according to the NASA, the agency possessed “a handful of F-106s were retained . . . for test [the Eclipse programme] purposes through 1998.”
An ancillary connection to the flying machines referenced above was established by John Dyke, a civilian employee of Wright-Patterson Air Force Base. The Dyke Delta JD1 first flew on 17 July 1962. The JD2, a larger and more powerful mark, first took wing on 19 July 1966. Online at least two statements contend that the JD-2 structure was evaluated at Wright-Patterson Air Force Base’s Structural Laboratory and the University of Utah. However, Military Aviation Chronicles contacted John Dyke and the designer stated that if the aforementioned information was true he was unaware of the testing.
When considering the appropriateness of the delta symbol for USSF, one should also not forget the Delta launch vehicles which continue to play important roles in USAF and USSF operations. The Boeing.com Delta Rocket webpage states the following: “Delta’s history stretches back to the late 1950s when the U.S. government, responding to the Soviet Union’s launch of Sputnik in 1957, contracted for development of the rocket. These early Delta rockets derived their design from the Thor, USAF’s intermediate-range ballistic missile. The first successful Delta launch was of NASA’s ‘Echo 1A‘ satellite on Aug. 12, 1960.”
Subsequently, the ‘Telestar 1‘ satellite was launched from USAF’s Cape Canaveral Air Force Station in Florida on 10 July 1962. The USSF 45th Space Wing at Patrick Air Force Base, Florida continues to rely upon ‘Delta IV’ and ‘Delta IV Heavy’ launch vehicles.
USAF’s former Space Command was redesignated, at the urging of President Donald J. Trump, as USSF on 20 December 2019. USAF is, through its USSF associate, continuing to work amongst the stars and the legacies of the delta’s connections will thereby forever be emblematically displayed.
