N623SW

This airframe, registered as N623SW, is a Boeing-built narrowbody delivered in 1996 with manufacturer serial number 27933. The airframe is identified as a Boeing 737-3H4 and is owned by NORTHROP GRUMMAN SYSTEMS CORP, a corporation based in El Segundo, CA, US, which places the aircraft in a corporate-government contractor role rather than commercial airline service. Registry records list the aircraft as a United States-registered fixed-wing multi-engine platform; notable administrative entries include its corporate ownership and operator/home base linkage to El Segundo. Condition and valuation specifics are not published here, but the airframe’s configuration and age frame typical mid-life maintenance and asset-management considerations.

This specific Boeing 737-3H4 is recorded with a single-class high-density cabin for 149 passengers, with some records alternatively reporting a Y137 layout indicating variations in seat count across registries; the primary cabin role is consistent with high-capacity transport. Operated from the owner’s base in El Segundo, CA, the aircraft would typically be deployed on short- to medium-range missions within its published 2,255 nm range and cruise at approximately 430 kts, suitable for shuttle, charter, or corporate logistics tasks. Avionics and special mission fits are not detailed here; maintenance considerations for this airframe reflect its mid-1990s manufacture and the CFM56-3B1 engine series common to the Classic 737 family.

The Boeing 737-300 series occupies a market niche for reliable short- to medium-haul transport with robust commonality across the Classic 737 family, competing historically with early-generation Airbus A320-family variants in capacity and mission flexibility. For corporate or government owners like NORTHROP GRUMMAN SYSTEMS CORP, the airframe offers a cost-effective, high-density seating option and a well-understood maintenance profile tied to the widespread CFM56-3B1 engine fleet. Resale and long-term support considerations for a 1996-built 737-3H4 center on airframe fatigue cycles, parts availability for Classic-series components, and potential cabin reconfiguration demands driven by operator mission changes.
