The integrated system review validated that Lockheed Martin’s T1TL ground and space designs meet all mission requirements and can proceed to production. During the CDR, which took place eight months after a successful preliminary design review, Lockheed Martin and SDA worked closely to thoroughly validate the company’s T1TL satellite and ground designs, to include supplier designs. SDA also contracted Lockheed Martin to build 10 Tranche 0 Transport Layer (T0TL) satellites, which are ready for launch this summer.
