Rocha-Contador

 is a southwest Alutran company involved in the design, development, manufacture, and servicing of civil s and. The company has dual headquarters in Ventora and Watan as well as design and production facilities in both countries. The company was founded in 1933 when the founders of Ventoran Aviones Rocha SA and Watanese Aviação Contador agreed to form a joint venture.

At the time, there was no mechanism for a company to have dual headquarters in different countries, but the success of the venture resulted in laws being passed in the respective countries so the company today has its headquarters in both Nicó, Barcon, Ventora, and Alhadas, Matania, Watan. The current co-chairmen are Ventoran Mireia Asun y Rocha Eche, Rocha's granddaughter, and Watanese Inácio Gouveia.

RC-62
The is a long-range   introduced in 1967 and substantially updated in 1974. Originally designed to carry at least 165 coach-class passengers more than 4500 km, the upgrade allowed for up to 198 passengers in a six-abreast cabin. Although the aircraft enjoyed commercial success, it has become dated and few airlines continue to operate the RC-62. An executive cabin version remains popular with some governments, notably Ventora, for senior governmental official travel.

RC-76
Rocha-Contador's best known workhorse is the. First flown in 1971, the remains popular with a number of militaries because of its capacity and ability to operate from relatively austere airfields. The company has continued to support the airframe, with the latest improvement, the RC-76MD90, entering service in 2014. A number of airlines continue to fly the RC-76, particularly in cargo service.

Several variants of the airframe exist. These include RC-76B firefighting tanker, RC-78 aerial refueling tanker, RC-82 airborne warning and control aircraft, RC-84 maritime search and rescue aircraft, and RC-76S medical/hospital aircraft.

RC-96
First flown in 1988 and certified in 1992, the is the company's long-haul  airliner. It replaced the from the mid-1970s which is no longer in commercial service. Depending on model, the RC-96 seats from 262 to 436 in three, two, or single class cabins. The airliner has a range of 10000 km to 12800 km at 870 km/h. The freighter versions have a range of 5000 km. The RC-96-300 uses a flight deck crew of 3 but the other versions do not require a flight engineer.

Current variants include:
 * RC-96-300 – airliner seating 237, 263, or 300 in triple, double, or single class cabin
 * RC-96-300M – airliner seating 307, 340, or 420 in triple, double, or single class cabin
 * RC-96-300C – freighter with a cargo capacity of 71 t
 * RC-96-400 – airliner seating 315, 386, or 436 in triple, double, or single class cabin
 * RC-96-400C – freighter with a cargo capacity of 92 t

Rocha-Contador is working on an aerial refueling tanker, the RC-96-400T, with first flight expected in 2022. The design calls for it to carry 65 tons of fuel for a range of 3500 km. The Ventoran Armed Forces have expressed interest in the tanker to replace its RC-78 aircraft which only carry 40 tons of fuel with a 3000 km range.

Another variant under development is a version to reduce fuel consumption and maintenance costs. The company expects first flight in 2025. Several airlines have expressed interest in the concept.

RC-114
In the 1980s, the company decided to enter the regional air route market and developed the {{wp}turboprop}} RC-114. It first flew in 1990 and entered production in 1992. The aircraft seats 52 to 68 passengers, typically in a single or double class cabin and has a flight deck crew of two. It can fly about 1000 km at a cruising speed of 470 km/h up to a service ceiling of 7620 m.
