Model & Market Context
This airframe, registered as N773LM, is a 2014-built Gulfstream G450 (GIV‑X) with serial number 4311. The airframe is registered in the United States and is recorded as owned by ALKO 250 LLC, an LLC based in San Francisco, CA, US, which appears as the current registered owner. The aircraft’s documented market valuation is $16,250,000, reflecting its condition and equipment pedigree for a mid‑2010s G450. No additional ownership transfers or notable registry actions are published beyond the current LLC registration.
The cabin of N773LM is fitted in a 14‑passenger layout with a forward galley; a forward 4‑place club; a mid‑cabin 4‑place conference/dining arrangement; and an aft configuration consisting of a 4‑place divan opposite two single club seats. Avionics are based on Honeywell PlaneView / Primus Epic with four DU‑1310 displays and options for heads‑up display (HUD) and enhanced vision system (EVS), supporting advanced operational capability in varying visibility conditions. Typical missions for this airframe would include long‑range corporate or private transport given the 4,350 nm range and high cruise speed; operations are expected to originate from or be managed out of the owner’s San Francisco, CA location unless operated by third‑party flight departments or charter operators. Maintenance considerations follow G450 fleet practices, particularly attention to Rolls‑Royce Tay engine support and Honeywell avionics lifecycle elements installed on this airframe.
The Gulfstream G450 (GIV‑X) occupies a long‑range, high‑speed corporate jet niche, offering transcontinental capability with a cruise near 459 kts and a service ceiling of 45,000 ft. In the marketplace it competes with other large‑cabin, long‑range business jets; its common competitors include late‑model Bombardier and Dassault offerings of similar mission capability. Buyer and charter demand for a well‑equipped 2014 G450 often emphasizes avionics upgrades, engine maintenance history, and interior configuration; resale considerations for N773LM include its documented equipment fit (HUD/EVS option capability) and the recorded valuation of $16,250,000.
