Gulfstream G550
N38NG · ICAO: A45A24 · Heavy jet

Northrop Grumman Corporation — one of the five US defense primes, ~$41B revenue, ~97,000 employees. Corporate HQ at 2980 Fairview Park Drive, Falls Church VA; Aeronautics Systems is headquartered at 1 Hornet Way, El Segundo CA, the address on all four aircraft registrations. Principal programs include the B-21 Raider, the LGM-35A Sentinel ICBM, the James Webb Space Telescope bus, Triton and Global Hawk, and the F-35 centre fuselage.
Fleet of four, all held directly by Northrop Grumman Systems Corp rather than through a trustee — unusual candour for a company of this size, and the reason this entry ships without a `planeOwner` override. N38NG (2015) and N37NG (2018) are Gulfstream G550s, the standard large-cabin corporate pairing for a prime with sites strung between California, Utah, Alabama, Maryland and Florida. N37WH is a 1994 Gulfstream IV, the oldest airframe of the four and the one inherited from the Northrop/Grumman-era flight department. N804X is the odd one out: a 1999 Bombardier CL-600-2C10 — a CRJ-700, and MSN 10002, the second of the type ever built — operated as a flying testbed rather than as transport.
Nothing on a military registration is tracked here. Published sightings put N38NG at Los Angeles repeatedly, plus Dallas/Fort Worth, Offutt AFB, Gulfport, Stansted and Luton, Warsaw and Ottawa — the travel pattern of a prime servicing customer sites and overseas programs, not a single-hub executive shuttle.
Note · We track Northrop Grumman's planes, not Northrop Grumman in person. Flight data shows when and where each plane flew. It does not show who was on board.
We do not see it in the air right now. The last flight we tracked for Northrop Grumman's Gulfstream G550 (N38NG) landed at Cecil Airport (KVQQ) on October 13, 2026. Follow it on the live jet tracker map.
The map shows where Northrop Grumman's planes have flown. Each dot is a recorded position.
Over the last 37 completed flights we tracked, Northrop Grumman's private jets spent about 105 hours in the air. We estimate those flights put out 469.2 metric tons of CO₂.

We track 4 private jets for Northrop Grumman. Each one is listed below with its tail number and hourly CO₂.
These are the last 37 flights we tracked for Northrop Grumman's private jets, newest first. Open a flight to see its route map, time in the air, top altitude and speed.
Yes. We track 4 planes linked to Northrop Grumman: a Gulfstream G550 (N38NG), a Gulfstream G550 (N37NG), a Gulfstream IV (N37WH) and a Bombardier CRJ-700 (N804X). The flight log on this page comes from public ADS-B signals. It shows where the planes went, not who was on board.
Northrop Grumman flies these planes: Gulfstream G550, Gulfstream IV and Bombardier CRJ-700. The tail numbers are N38NG, N37NG, N37WH and N804X. You can track each one live on this page, along with its flight history and CO₂.
Northrop Grumman owns 4 tracked planes of 3 different types: N38NG (Gulfstream G550), N37NG (Gulfstream G550), N37WH (Gulfstream IV) and N804X (Bombardier CRJ-700). That count only covers planes we can tie to Northrop Grumman through public registration and ADS-B records. A plane held through an undisclosed company, or one that is chartered, would not show up here.
Northrop Grumman flies a Gulfstream G550, tail number N38NG. It is in the Ultra Long Range class. It can fly 6,750 nautical miles without stopping and seats up to 19 people. We also track 3 more planes on this page: Gulfstream G550 (N37NG), Gulfstream IV (N37WH) and Bombardier CRJ-700 (N804X).
Northrop Grumman flies a Gulfstream G550 (N38NG). Used ones usually ask $14–25 million. These are mid-2026 market figures, not an appraisal of this plane. Its real value depends on its flight hours, engine maintenance plan and cabin layout.

Northrop Grumman's private jets have these tail numbers: N38NG (Gulfstream G550), N37NG (Gulfstream G550), N37WH (Gulfstream IV), N804X (Bombardier CRJ-700). Each tail number links to a live tracking page. There you can see the plane's flight history, fuel burn and CO₂.
About 3,939 kg for every hour in the air. Northrop Grumman's Gulfstream G550 (N38NG) burns roughly 410 gallons of jet fuel an hour. That is about the same CO₂ as driving an average car 9,749 miles.
Northrop Grumman's home airport is Los Angeles Intl (KLAX / LAX). Frequent stops include KIAD, KDFW, KOFF and KGPT.
About 469.2 metric tons of CO₂ over 37 tracked flights and 105 hours in the air. We start with the flight times from public ADS-B data. We multiply each hour by the maker's fuel burn figure. Then we apply the EPA standard of 9.57 kg of CO₂ per gallon of jet fuel.
Yes. The FAA requires planes with transponders to broadcast their position over ADS-B, and the signal is not encrypted. We collect that public data from adsb.lol and ADSB.fi, two open flight-tracking networks. News outlets and university researchers use the same kind of data. Our methodology page explains how it works.
