Den GAF Jindivik er en radiostyret måldrone produceret af Australian Government Aircraft Factories (GAF). Navnet er fra et aboriginsk australsk ord, der betyder "den jagede". To manuelt styrede prototyper, blev bygget som GAF Pika (Projekt som et proof of concept til test af aerodynamik, motor og radiostyringssystemer, serienummer A92-1/2, 'B-1/2'. Det radiostyrede Jindivik blev oprindeligt betegnet som Project B og modtog serier i A93-serien. Pika er et aboriginsk australsk ord, der betyder flyver

General Characteristics and Role
The GAF Pika was a single-seat, manned, experimental jet aircraft developed by the Government Aircraft Factories (GAF) in Australia. Its primary and sole role was to serve as a proof-of-concept testbed for the larger Jindivik pilotless target drone program. The Pika (an Aboriginal Australian word meaning “flier”) was essentially the Jindivik airframe modified with a cockpit, side air intakes (to clear space for the pilot), and a conventional retractable tricycle undercarriage. Only two prototypes were built (A93-1 and A93-2). By flying the Pika first, engineers could safely test the Jindivik’s unique aerodynamics, the performance of its jet engine, and the complex radio control systems before attempting unmanned flight, making it the only Australian-designed and built manned jet aircraft to date.

| National Origin | Australien |
| Producent | Government Aircraft Factories (GAF) |
| First Flight | October 31, 1951 (or November 4, 1950, sources vary) |
| Besætning | 1 (Pilot) |
| Max Takeoff Weight | Approx. 1,315 kg (2,900 lb) |
| Længde | 7.08–7.49 m (23 ft 3 in – 24 ft 7 in) |
| Vingefang | 5.79–5.8 m (19 ft 0 in – 19 ft 0 in) |
Powerplant and Performance
- Engine: 1 x Armstrong Siddeley Adder ASA.1 turbojet engine.
- Thrust: Approx. 3.9 kN (1,050 lbf).
- Maximum Speed: Approx. 756 km/h (470 mph).
- Service Ceiling: Approx. 9,754 m (32,000 ft).
- Endurance: Limited to around 30 minutes due to the reduced fuel load necessitated by the pilot’s cockpit and undercarriage.
- Unique Purpose: The Pika could be flown manually by the pilot or controlled remotely by a ground station, providing crucial training for the future Jindivik operators.
- Air Intakes: Unlike the subsequent Jindivik (which had a dorsal intake), the Pika featured two side-mounted air intakes.
Service History and Legacy
- Test Program: The two prototypes logged over one hundred flights during testing at the Woomera Rocket Range in South Australia.
- Key Findings: The trials confirmed the Jindivik’s aerodynamic stability and performance envelope. One significant result was proving that the final Jindivik design did not require a rudder, leading to cost and weight savings.
- Successor: The knowledge gained from the Pika directly led to the successful development and mass production of the GAF Jindivik, which became a globally exported, high-altitude target drone used by Australia, the UK, Sweden, and the US Navy.
- Final Status: The last flying Pika (A93-2) ended its flying career in 1954. The sole surviving prototype is preserved and on public display at the RAAF Museum in Point Cook, Victoria.
