The collaboration builds on the Stairway to Seven mission, also known as Alpha Flight 7, conducted in March 2026.

GeneralValue 3.0May 4, 2026Lockheed Martin, Firefly, and Seagate Partner for Sea-Based National Security Launch

Firefly Aerospace carried out Stairway to Seven, the seventh launch of an Alpha rocket.

Firefly Aerospace provided a livestream of the Alpha Flight 7 "Stairway to Seven" test flight.

GeneralValue 2.3Mar 12, 2026RT by @GewoonLukas_: We have liftoff of Alpha Flight 7 Stairway to Seven test flight! Catch the livestream here:

Firefly launched the "Stairway To Seven" mission on its Alpha vehicle designated FLTA007.

GeneralValue 4.0Mar 12, 2026So it turns out that FLTA007 did in fact carry a satellite for Lockheed Martin. The payload has been cataloged as "ICOR SV", which we hadn't heard about before. Given the secrecy, I'd say it's likely demonstrating more classified technologies compared to the previous tech demo's.

Firefly Aerospace launched the Stairway To Seven mission on Alpha FLTA007 on March 12, 2026.

PlanCapabilityValue 4.5Mar 12, 2026It may have taken several delays, but Firefly successfully launched the "Stairway To Seven" mission on Alpha FLTA007! Apparently they did carry payloads for Lockheed Martin, but it sounds like these are hosted experiments rather then actual deployable satellites.

Firefly Aerospace launched an Alpha rocket on Flight 7 (FLTA007), a test flight named "Stairway to Seven".
