- OBBBA-funded White Sands construction projects extend workload through 2026 and deepen incumbency.
What critics are saying
- TEST3 ends September 30, 2026, forcing Sierra Lobo into a critical recompete.
- NASA contract concentration makes one protest loss or technical failure financially severe.
- Losing Glenn, Stennis, or White Sands work would threaten Sierra Lobo's business model.

Therefore, before delving deeper into TASEs, we must start with Stirling Engines.What is a Stirling Engine?The name comes from its inventor, Reverend Robert Stirling, who came up with an external heat engine vastly different from the traditional internal combustion engines used in cars. It is different in its use of the stirring cycle, which has three core features.Gasses used inside a Stirling engine never leave the engine. Unlike gasoline or diesel engines , these engines do not have exhaust valves to vent high-pressure gasses. It does not have explosions taking place, either
