Japan J-LEO — MDA Space emerges as third contender; decision due June 30 (tomorrow).
Not filed to a thread
As the brief logged it
Prior framing was binary (Rakuten-AST vs. KDDI-SpaceX). MDA Space (Canadian constellation manufacturer) is now confirmed as a distinct third candidate. MDA's case: neither a Musk-controlled nor an AST-controlled constellation, positioning as a non-US-sovereign option for Japan's autonomous connectivity requirement. 700 MHz ruling (June 24) still favours Rakuten-AST. Decision is MIC's call, expected June 30; soumu.go.jp English press release is the primary source. Either KDDI-SpaceX or MDA outcome negates the Rakuten-AST thesis; Rakuten-AST win validates Japan sovereign D2D precedent supporting COM(2026)311 architecture.
