SDA Awards Contracts to York Space Systems and Tyvak; Viasat Protests
What happened
The Space Development Agency awarded contracts to York Space Systems and Tyvak. This decision prompted a protest from Viasat. Separately, officials stated that the Space Force will reinstate Derek Tournear as SDA director on April 17, following an investigation into past contracting practices involving a contract awarded to Tyvak last August.
