The system could measure spray droplets down to 5 micrometers. In the 1980s, a spray test rig was installed in Cell 12 to study multi-phased flow and fluid spray characterization. The setup included a pressurized system that supplied air flow to both the experimental combustors and ejectors, which provided a vacuum for the wall diffuser bleed flows. In the late 1960s, a test rig was built inside Cell 12 to study combustors with short diffusers. The cell was damaged by explosions several times during this period. The cell was used for film cooling investigations in the 1940s, then combustion vibrations in the 1950s.

The upgraded test cell and control room could operate as an autonomous facility to expedite testing. In 1989, the Low Thrust Propulsion Facility was built for testing of gaseous hydrogen and gaseous oxygen thrusters in simulated altitudes. In the late 1970s, a flametube test rig was installed in Cell 11 to support combustion testing of coal-based fuels for the Department of Energy. The cell appears to have been idle for a number of years until it was expanded in the late 1960s for testing of combustors for aircraft engines. The Rocket Tunnel simulated heating at hypersonic speeds. In the mid-1950s, the cell was extended southward to accommodate a new 5,000 pound -thrust rocket-powered supersonic tunnel. In the 1940s and early 1950s, Cell 11 contained a test stand for firing 100- and 500-pound-thrust liquid- fuel rocket engines aimed downward at a 45-degree angle for fuel evaluation and film cooling tests. For the first few years of operation, Cell 11 was named Cell 4, Cell 12 was Cell 3, Cell 13 was Cell 2, and Cell 14 was Cell 1. Each of these single-story cinderblock buildings included the two test cells back-to-back facing opposite directions, two small control rooms, and a large service area. Cells 11 and 12 were located in Building 35-4 at the front, left area of the complex, while Cells 13 and 14 were in Building 35-5 to the right. When it began operation in 1945, the Rocket Lab included four 20- by 8-foot test cells to conduct its testing. Rocket Lab Space Combustion Facilities (1994).Rocket Lab Test Cell Descriptions (1993).In addition, only a small operations crew was required to conduct most testing.
The simple design of the buildings made them highly-adaptable to perform an array of testing.
They were all supported by advanced data acquisition and control systems. The individual cells were somewhat homogeneous physically, the installations and test equipment were unique. The Rocket Laboratory complex included ten test cells that were constructed in the 1940s and 1950s but were improved and modified over the years to meet changing test requirements.
