Development Roadmap & Vision
A Decade-Long Programme from Physics to Flight
Technology Readiness
LASSTOV is currently at Technology Readiness Level (TRL) 2–3 for the integrated vehicle system, with individual subsystem technologies at TRL 3–5. The core condensation technology has undergone independent technical assessment. The INIJEVID control system has been prototyped and tested. Aerodynamic principles are grounded in established fluid mechanics.

Near-Term Revenue Pathways
While LASSTOV is a long-horizon programme, Entropy Engines' adjacent technology portfolio provides near-term revenue and technology validation through:
Validates core drag reduction technology on commercial aircraft
Aviation retrofit programme
Funded Orkney deployment; Cranfield-assessed; UK patent granted
REVFRACC carbon capture
UKRI-funded deployment; data centre commercial discussions underway
INIJEVID cooling systems
3MW project pipeline progressing toward commercial deployment
TIPA solar energy
These programmes generate revenue, validate platform technology, build engineering capability, and attract the partnerships required to advance LASSTOV through its development phases.
Long-Term Vision
LASSTOV's ultimate aim is to deliver aircraft-like operations with a weekly mission cadence per vehicle, conventional runway operations, and a cost per kilogram that opens space to industries, organisations, and applications not yet conceivable within current launch economics.
Target Operating Model
Each vehicle: weekly mission cadence. Payload to GEO: 275 tonnes per mission. Cost per kg: $20–$100. Turnaround: days, not months. Infrastructure required: a runway.
