N707MQ

The airframe bearing tail number N707MQ is a Boeing 707-368C built in 1977 with manufacturer serial 21368. The airframe has been converted into a tanker as a KC-707A configuration and is registered in the United States. Ownership is recorded to the corporate entity AIRCRAFT ENDEAVORS LLC, located in San Antonio, TX, US, and the aircraft is maintained in a converted tanker configuration rather than a standard passenger executive layout. Notable registry action includes its current registration to AIRCRAFT ENDEAVORS LLC, and condition highlights emphasize its role as a purpose-converted refuelling platform rather than a line-fit civil transport.

The cabin of N707MQ is in a converted tanker configuration with refuelling gear installed and is explicitly not a standard passenger executive layout. Avionics fit and specific mission avionics are Not published. Typical mission profiles for this airframe emphasize air-to-air refuelling and long-range ferry or repositioning flights, taking advantage of its 5,750 nm range and cruise speed around 525 kts, with operations staged from its owner’s base in San Antonio, TX, US. Maintenance considerations for this airframe focus on sustaining specialized refuelling systems and maintaining four Pratt & Whitney JT3D-3B engines in a legacy airframe, with cabin and systems inspections tailored to tanker hardware.

As a Boeing 707-368C airframe converted to tanker specification, N707MQ occupies a niche where legacy jetliner performance—long range, high cruise speed, and substantial seating/space capacity—has been adapted for aerial refuelling missions. Comparable roles might otherwise be filled by purpose-built tankers or more modern tanker conversions; however, the 707 conversion offers a balance of range (5,750 nm) and speed (525 kts) with proven airframe robustness. Buyer and operator demand for such conversions is specialized, with resale and ongoing maintenance considerations driven by age, availability of JT3D-3B engine support, and the continued utility of installed refuelling equipment.
