In short: While famous as a commercial icon, the Boeing 707 found a second life as the C-137 Stratoliner. Beyond transporting presidents, these versatile airframes were modified into airborne command posts, surveillance platforms, and refueling tankers, serving critical roles from the Apollo space program to the management of global nuclear forces.

The Boeing C-137 Stratoliner originated as a military adaptation of the 707 jet airliner. Although the United States Air Force initially procured only three VC-137A models in 1959, the platform's reliability led to its expansion into a diverse fleet. These aircraft were frequently re-engined and redesignated as their roles evolved from VIP transport to specialized military missions. The most iconic of these were the VC-137C presidential transports, known by their call signs SAM 26000 and SAM 27000, which served multiple administrations before their retirement in 1998 and 2001, respectively.

The versatility of the 707 airframe allowed it to support highly technical operations. Variants like the E-3 Sentry provided all-weather surveillance, while the E-6B TACAMO served as a vital communications link to the nation's fleet of ballistic missile submarines. Other modifications, such as the EC-18B, supported the Apollo space program as Advanced Range Instrumentation Aircraft. The military also utilized second-hand civilian 707s from carriers like American Airlines, TWA, and TAP Portugal, repurposing them for crew training and specialized command functions.

International air forces also adopted the platform to extend their operational reach. The Israeli Air Force, for instance, converted civilian 707s into 'Re'ems' capable of aerial refueling, cargo transport, and even medical equipment delivery during the 2020 pandemic. Despite the diversity of these missions, the C-137 remains distinct from the C-135 Stratolifter; while they share a common ancestor, the two aircraft possess different structural designs and fuselages. Today, several historic C-137 airframes, including those that once served as Air Force One, are preserved in aviation museums across the United States.
