Czech aircraft maker boosts Asian presence with Vietnam jet trainer deal
By: Jaroslaw Adamowski and Mike Yeo
WARSAW, Poland, and MELBOURNE, Australia — Securing the first Asian customer for its latest product, Czech aircraft maker Aero Vodochody has signed a contract to sell 12 L-39NG jet trainers to Vietnam's Ministry of National Defence. Deliveries are scheduled for the years 2023 to 2024, and Czech arms exporter Omnipol is acting as an intermediary for the deal.
“We are proud to announce this crucial and strategic cooperation which is an important milestone for the L-39NG project,” Jiří Podpěra, the president of Omnipol, was quoted as saying in a statement.
The value of the deal, which includes training, spare components and related logistics support, was not disclosed. The sale includes a range of related services such as pilot and instructor training, spares, as well as ground and logistical support equipment, the company said.
The Czech Ministry of Defence certified the jet trainer last September, paving the way for the L-39NG's exports. The move followed about 300 test flights on two flying prototypes and ground tests on two static prototypes, according to the producer. Since then, Aero Vodochody has managed to secure a contract to deliver four such aircraft in a light-attack variant to Senegal's Air Force.
Omnipol is a minority shareholder in Aero Vodochody, with a 49 percent stake. Hungarian businessman Andras Tombor holds the remaining 51 percent of the shares.
The L-39NG is a modernized version of the L-39 trainer that was originally introduced into service in 1970. The new aircraft features a host of improvements over the original design, with a modern glass cockpit, improved avionics and the FJ44 turbofan engine by U.S. manufacturer Williams International.
The Vietnam People's Air Force or VPAF currently operates older versions of the L-39, with an estimated two dozen aircraft still in service.
The announcement that Vietnam will acquire the L-39NG comes after the country ordered a similar number of Yak-130 jet trainers from Russia in early 2020. A news segment on Russian state TV from January showed a Yak-130 for Vietnam on the production floor of the Irkutsk Aviation Plant, which produces the jets.
It is likely that the VPAF will operate the L-39NG as a basic jet trainer, with the higher-performance Yak-130 acting as an advanced jet or lead-in fighter trainer.
Vietnam is one of six countries claiming ownership of the disputed Spratly and Paracel islands in the South China Sea, and has been one of the most vocal in pushing back against fellow claimant China's increasingly assertive military activities in the area.
The Vietnamese military still operates primarily Russian equipment, but has in recent years acquired transport aircraft from European manufacturer Airbus and taken delivery of surplus ships from the South Korean navy and U.S. Coast Guard.
An arms embargo on the country imposed by the United States following the end of the Vietnam War was lifted in 2016, and U.S. Navy ships, including aircraft carriers, have made port visits to Vietnamese ports in recent years.

NASA Seeks Lunar Gateway Resupply Proposals
Mark Carreau NASA has issued a request for proposals (RFP) from U.S. companies capable of carrying out up to $7 billion in re-supply missions to its planned lunar-orbiting, human-tended Gateway. The request asks for a service similar to how multiple commercial providers deliver pressurized and unpressurized cargo to and from the six-person International Space Station (ISS) under commercial resupply services contracts. The major difference is that the ISS orbits in a high inclination orbit about 250 mi. from the Earth's surface. The Gateway is to orbit the Moon in a near rectilinear halo orbit, an elliptical track that comes as close to the lunar surface as 1,875 mi. (3,000 km) and as far as 43,750 mi. Under the Gateway cargo RFP, the craft would remain parked at the Gateway for six months, followed by an automated departure and disposal. Responses to the RFP, issued Aug. 16, are due Oct. 1. Under the Artemis initiative unveiled by NASA earlier this year, astronauts will return to the lunar surface via the Gateway by 2024 as the agency pursues a sustainable presence by 2028 and prepares for the human exploration of Mars. Under the RFP issued through NASA's Kennedy Space Center (KSC), the agency is prepared to commit up to $7 billion to contract with multiple U.S. suppliers for 15 years on a fixed-price basis. Each resupply service would be assured at least two missions. NASA is asking RFP responders to address logistics, spacecraft design, cargo mass capability, pressurized volume, power availability for payloads and transit time to the Gateway. “We chose to minimize spacecraft requirements on industry to allow for commercial innovation, but we are asking industry to propose their best solutions for delivering cargo and enabling our deep-space supply chain,” said Mark Wiese, NASA's Gateway logistics element manager at KSC, in an Aug. 19 NASA statement. “In addition to delivering cargo, science and other supplies with these services, private industry also has the opportunity to deliver other elements of our lunar architecture with this solicitation.'' Once the initial contracts are awarded, NASA may issue additional lunar cargo contract opportunities to keep the operations competitive. With advance permission from NASA, its providers also may use mission capabilities to deliver, remove and/or return non-NASA cargo if the additional activities do not interfere with the prime mission. In late November, NASA announced the selection of nine U.S. companies under its Commercial Lunar Payload Services (CLPS) program, making them eligible to bid on the delivery of payloads to the lunar surface. The agency plans to invest up to $2.6 billion in CLPS over the next decade. https://aviationweek.com/space/nasa-seeks-lunar-gateway-resupply-proposals
