@CatSE___ApeX___ @SemperCitiusSDA "But only the 20 Gamma satellites will have four optical terminals and the Warlock payload." So one vendor. Twenty sats. All Warlock. Maybe more later. Does Warlock harbor the four optical terminals or the carrier sat? Replace Q/V with OT or put OT on top of sat? Or mixed?
