More info, S-2 project with the U.S. Army.
S-2 - Portable Power: Our S-2 project with the U.S. Army / TARDEC to develop a compact, multi-fuel 10-kWe auxiliary power unit continues to move forward. We expect to complete the proof-of-concept stage on this engine by this summer, with the balance of our $1.4 million fees being paid during this time. We are currently martialing support and interest for Phase 2 of this project, which will consist of engine "hardening" over the following 24 month period, and could provide Cyclone with several million dollars more in revenue.
