N91011

This airframe, tail number N91011, is a 1983-built Lockheed L-1011-500 TriStar (L-1011-385-3), serial 293B-1241, manufactured by Lockheed Corporation. It is recorded as registered in the US and is owned by Northrop Grumman, based in Victorville, CA, US. The airframe's documented ownership places it in corporate government/defense service rather than scheduled airline use; owned and held by Northrop Grumman at Victorville, CA is the principal notable custody detail. Valuation and formal condition assessments are Not published.

Specific cabin layout and passenger seating for this individual airframe are Not published. Avionics fit and interior configuration details are not published for this serial; as a wide-body tri-jet of its series it would generally be adaptable to mixed passenger/cargo or corporate support roles, consistent with ownership by a large defense contractor. Recorded operational basing places the aircraft with Northrop Grumman in Victorville, CA, indicating local maintenance and storage activities are likely centralized there. Routine mission profiles inferred from the aircraft's performance envelope (long-range cruise and high ceiling) suggest capability for extended ferry flights, test support, or non-scheduled long-distance transfers, though specific operational tasking is not published.

The Lockheed L-1011-500 TriStar (L-1011-385-3) occupies the late-generation wide-body tri-jet niche, offering long-range capability and high-altitude cruise performance appropriate for intercontinental sectors. With three Rolls-Royce RB211-524B powerplants rated at 50,000 lbf each, the type emphasizes redundancy and sustained cruise performance (noted here at 525 kts and 5,600 nm range). In the secondary market the family competes historically with other wide-bodies of its era, and contemporary buyer interest gravitates toward specialized operators, corporate fleets, or conversion to non-passenger roles; maintenance and resale considerations for this airframe reflect its age (1983 build) and tri-jet logistics, with preservation and parts support typically concentrated among legacy operators and large corporate/defense owners.
