MDA CHORUS combines the operating RADARSAT-2 asset with planned C-band and X-band SAR satellites. On September 16, 2026, MDA introduced COMMAND for archive access, planning and tasking, COMMAND PRO for a customer-integrated regional ground station, and INTELLIGENCE for geospatial analytics. The new satellites remain scheduled for launch in late 2026. The advertised 700 km broad-area swath and sub-metre spotlight resolution describe different imaging modes, not simultaneous performance from one acquisition.

These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Product portfolio announced September 2026; RADARSAT-2 is in orbit, while the two new spacecraft remain pre-launch. Product introduction and ground-facility readiness do not establish completed constellation operations.
Commercial availability
Customer engagement and planned access are marketed through MDA. Confirm which data sources are operating, delivery dates, imaging modes, tasking rights and ground-station requirements.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
MDA CHORUS Synthetic Aperture Radar Constellation may help teams working on Future submarine operational capability by contributing to maritime and undersea operations, Arctic and northern operations, and detection and situational awareness.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
