It is not flying anything inside the current manifest window, though the register lists 1 scheduled launch under its own name.
Flight record
Launch statistics
Counts are launches filed under NGSS’s own name in The Space Devs’ Launch Library register. They are not a count of missions or payloads: a spacecraft that flew on a contracted vehicle is credited to the operator that flew it.
Who flies for them, and who they fly for
An operator owns the rocket and runs the count, and it is the operator’s name the launch schedule filters by. A customer funds the mission, supplies the payload and buys the ride. Plenty of organisations are both. NGSS is counted below in whichever role the current manifest actually gives it.
Manifest role
No scheduled flight in the current window names NGSS while being operated by somebody else.
How this is counted: a scheduled launch is treated as a customer flight when this organisation’s name or abbreviation appears in the launch name, mission name or programme and somebody else is flying it. Mission descriptions are not searched, and the window is one batch of the next launches worldwide, reaching to 2026-12-31 00:00:00Z — so both counts are a floor, not a complete manifest.

Manifest
NGSS is not flying anything inside the current manifest window, which reaches to 2026-12-31 00:00:00Z. The register lists 1 scheduled launch under its own name, with dates further out or not yet filed.
All upcoming launches“T-0 known to” is the register’s own precision on the launch time — a date good only to the month is shown as such rather than counted down as if it were exact. A go-probability appears only where the operator published one for that flight; Delta-V does not calculate it and it is not a forecast made here.

- How many launches has Northrop Grumman Space Systems flown?
- Northrop Grumman Space Systems has 17 launches on record under its own name, of which 17 succeeded and 0 failed. The register counts launches flown under an operator's own name, not missions or payloads it contributed to.
- What is Northrop Grumman Space Systems's success rate?

- Does Northrop Grumman Space Systems fly its own rockets, or buy launches from another operator?
- Northrop Grumman Space Systems has 17 launches flown under its own name in the launch register. It is not the operator on any flight in the current manifest window. An operator owns the rocket and runs the count; a customer funds the mission, supplies the payload and buys the ride. The operator filter on the launch schedule lists only the former, which is why a well-known agency can be central to a flight and still not appear on it.
- Where is Northrop Grumman Space Systems based?
- Northrop Grumman Space Systems is based in United States of America and the register classifies it as a commercial operator. It was founded in 2015.
