UK Rocketry Certifications

Why Certify?

High-power rocketry in the UK is governed by the UK Rocketry Association (UKRA) in cooperation with the Civil Aviation Authority and local clubs. Certification gives you:

• Access to larger rocket motors (H-classes and above).
• Insurance coverage through UKRA for public launches.
• Credibility with mentors, suppliers & sponsors.
• Motivation to design, build and finish your own rocket.

Level 1 — Your First Taste of HPR

Motor limits: H or I class (impulse ≤ 640 N·s)
Altitude envelope: typically < 3 000 ft AGL at most UK sites

Objective — prove you can build & recover a high-power rocket safely.

• Single-stage rocket using solid composite motor.
• Recovery by single parachute or streamer is acceptable.
• No electronics required, but an altimeter adds polish.
• RSO (Range Safety Officer) inspects build quality & signs off.

Level 2 — Bigger Motors, Dual Deployment

Motor limits: J or K class (impulse ≤ 5 120 N·s)

Objective — demonstrate competency with electronics & more energetic motors.

• Dual-deployment recovery is mandatory (drogue at apogee, main at low altitude).
• Electronics bay using commercial altimeter(s) or custom-built hardware.
• Better structural margins to survive higher dynamic pressure.
• Documented flight predictions & stability margin calculations.

Level 3 — Expert Status

Motor limits: L or M class (impulse ≤ 40 960 N·s)

Objective — plan, document & execute a complex project under mentorship.

• Written project proposal reviewed by UKRA L3 committee.
• Structural analysis, flight stability, and recovery simulations.
• Redundant electronics (at least two independent altimeters).
• Full reports before & after flight; photographic evidence of build process.

On successful flight & documentation, you join an elite < 200-person community of UK L3 flyers — opening doors to hybrid & liquid propulsion projects, sponsorship deals, and outreach opportunities.
