/ Upcoming Milestones

View all →

Execute SDA satellite programs after passing TRKT3 SRR

Build and deliver the 18-spacecraft Tracking Layer Tranche 3 constellation for the Space Development Agency under Rocket Lab's $1.3B SDA prime work. The May 27, 2026 System Requirements Review remains the last publicly confirmed milestone; as of September 13, 2026 no Preliminary or Critical Design Review has been announced, with those the next gates ahead of spacecraft delivery. Mynaric CONDOR Mk3 laser links are produced in-house.

2026-2027

Sustain Electron cadence toward the 100th launch

With 96 Electron missions flown through the September 19, 2026 'Owl By The Dozen' dedicated Synspective StriX-12 launch (Rocket Lab's 17th launch of 2026), sustain Electron's record 2026 tempo across commercial, civil, and defense customers toward the company's 100th launch milestone. Remaining constellation bookings include iQPS (9 dedicated missions remaining on its total 18-launch Electron bookings, running through 2030) and Synspective (further missions booked to complete that constellation by decade's end). A HawkEye 360 Electron mission is listed no earlier than September 30, 2026.

2026

Convert backlog into higher launch cadence

Turn a record $2.36B of backlog (as of Q2 2026) into higher Electron and HASTE flight tempo across constellation, agency, national-security, and hypersonic missions; Rocket Lab guided to another record revenue quarter in Q3 2026 and reported more than $1B in additional new contracts signed since the quarter closed. The new GHOST containerized launch system, unveiled August 10, 2026 with its first site at Kodiak, Alaska, is aimed directly at expanding cadence for responsive and national-security missions.

2026-2028

Build & launch the first GEO satellites for U.S. Space Force

Design, build, integrate, and operate two geostationary satellites hosting the Heimdall space domain awareness payload under a $90M Space Systems Command contract - Rocket Lab's first GEO satellite production program. No public schedule update (PDR/CDR/delivery date) has been announced since the May 21, 2026 award as of September 13, 2026.

2026-2028

Blue Ring first operational mission

Launch the first full Blue Ring mission, expected to become the first fully commercial GEO space-domain-awareness mission, carrying Optimum Technologies' Caracal sensor with Scout Space's Owl payload and internal payloads. Blue Origin has integrated the flight vehicle's primary structure, internal harnessing, and core propulsion module, but launch timing remains gated by New Glenn's return to flight after the LC-36 explosion; reverified September 12, 2026, no firmer date has been reported, though NASA's Sept 1 award of a Blue Ring-based Mars Telecommunications Orbiter (delivery by Dec 31, 2028) adds a second Blue Ring-derived flight in the same window.

2026-2027

Scale SciTec Golden Dome SBI work

Execute SciTec's Space-Based Interceptor OTA under U.S. Space Force Space Systems Command, building software, sensing, and AI for the Golden Dome space-based missile defense layer, with capability integrated into the architecture targeted by 2028. SciTec's other Space Force work (CBC2 data fusion and the $93.7M GBARD radar-digitization OTA) remains in execution; Firefly has posted no new Golden Dome contract update since the May 4, 2026 SBI announcement.
