Northrop Grumman Vertical Engine Test Stand (VETS)

Rocket and laser testing; capability to test at sea level or at altitude using steam ejector system to simulate altitude during testing.

The VETS test facility was designed and built in the 1960s to evaluate variable thrust engine characteristics, combustion efficiency and stability, specific impulse, thrust chamber life, nozzle performance, and other operational and reliability aspects of rocket engines and components.

Engines tested at VETS can be tested at sea level or at altitude using the VETS steam ejector system to simulate altitude during rocket engine testing.

In the mid 1970s the VETS area was selected as the location for high energy chemical laser testing. Three laser test facilities were constructed in the VETS area to take advantage of the existing steam ejectors system.
