South Korean study finds Chinook upgrade more expensive than buying new helos

SEOUL — Research on the long-awaited upgrade of Chinook helicopters flown by the South Korean military shows it would be cheaper to buy new aircraft, according to a local lawmaker.

Rep. Min Hong-chul of the ruling Democratic Party revealed the result of the latest preliminary research on the Chinook upgrade during a parliamentary audit of the Defense Acquisition Program Administration on Oct. 20.

The lawmaker, who sits on the National Assembly's Defense Committee, said the research concluded in September that the cost of upgrading 17 of the 43 CH-47D Chinook helicopters would be about 1.35 trillion won ($1.2 billion), which is higher than the estimated cost of 1.22 trillion won for buying new ones.

The upgrade cost is partly driven by the fact that Chinook manufacturer Boeing no longer produces parts for older variants, like those owned by South Korea, so specially ordered parts could prove expensive, Min said, citing the research conducted by the Defense Agency for Technology and Quality, which is affiliated with DAPA.

Furthermore, some Korean military task equipment such as the Korean Variable Message Format data link cannot be installed on the upgraded helos due to incompatibility, the research suggested.

“A series of reverses and delays on decision-making have foiled key arms acquisition projects, including the Chinook upgrade,” Min said, expressing concern about an operational gap in military transport trainings and missions.

South Korea operates about 50 Chinooks, with some of them in service for up to 50 years. With some parts of the older Chinook no longer being produced, the South Korean fleet's operational rate has suffered, according to the lawmaker. For instance, the Air Force's Chinook utilization rate from the first half of the year was around 40 percent.

DAPA is expected to hold a meeting soon to decide whether to buy new heavy-lift helicopters rather than upgrade the existing fleet. But industry sources expect buying new helos would take more time and end up costing more, depending on the variant.

“To get Block I CH-47F Chinook cargo helicopters, which have been on the shopping list of the South Korean Army, the letter of offer and acceptance should be issued by July next year at the latest, but it would be very difficult to finalize the decision-making procedures within the timeline,” said Ahn Seung-beom, a military analyst and writer with Defense Times Korea. “[If it doesn't] buy Block I, South Korea has an option to get Block II, which is to be produced for the U.S. Army first, and then it could take more time and costs to get the up-to-date, heavy-lift helicopters.”

A source at Boeing told Defense News that both cost and an export license stand in the way of South Korea's CH-47F Block II purchase.

“The development of the CH-47F Block II is still underway, so the price cannot be expected at this moment,” the source explained on condition of anonymity. “The U.S. Army has yet to place an order for the new cargo helicopters, so it's unclear how many aircraft would be produced.”

It's also unclear if a foreign sale will receive approval, the source added. “The U.S. government strictly controls arms technology, so getting an export license for key weapons systems is a hurdle.”

    Companies line up to deliver Turkey hundreds of micro drones

    By: Burak Ege Bekdil ANKARA — The Turkish government has launched a competition to buy hundreds of multi-rotor micro drones, with scores of local companies having already expressed interest. SSB, Turkey's procurement authority, has said that the planned drones would be used in homeland security missions like search and rescue, surveillance and reconnaissance, remote sensing and mapping. An SSB official said all drone programs come with a “priority” tag. Under the multi-rotor micro drone program, SSB will procure a total of 499 units. Twenty-two companies have replied to SSB's Request for Proposal (RfP). “The level of interest [in the contract] and potential competition during the race reflects the vibrancy of Turkey's fast-growing drone industry,” said Özgür Ekşi, an analyst with C4Defense.com, a defense industry specialist. “Especially when you think that only a decade ago there was not a single drone maker in the country.” Turkey has long prioritized developmental and operation of unmanned systems for its military and for export. The Turkish military was largely dependent on the Israeli-made Heron unmanned aerial vehicles in its fight with Kurdish insurgents in early 2000s when the government-controlled Tusas Turkish Aerospace Industries (TAI) started working on the Anka, Turkey's first indigenous drone. In 2013 TAI won a contract from the Turkish government to supply 10 Ankas and ground control stations. The Anka, a medium-altitude, long-endurance drone, can fly at an altitude of 30,000 feet for 24 hours and can carry up to 200 kg payload. TAI later developed the armed and satellite-controlled versions of the Anka as the country's dependency on drones in its asymmetrical warfare against Kurdish insurgency deepened. The Anka has paved the way for the entry into the market of private sector players. Kale-Baykar, a consortium, has successfully developed the Bayraktar TB-2, a drone system that comes in unarmed and armed versions, and delivered to the military six systems in 2017. The Bayraktar uses the MAM-L and MAM-C, two mini smart munitions developed and produced by state-controlled missile specialist Roketsan. Turkey's local industry also is developing BSI-101, a SIGINT system, for the Bayraktar to end Turkey's dependence on U.S.-made SIGINT systems for drones. The Bayraktar can fly at a maximum altitude of 24,000 feet. Its communications range is 150 kilometers. The aircraft can carry up to 55 kilograms of payload. “We encourage private companies to spend more on drone R&D and come up with solutions cut for our specific (mostly asymmetrical) requirements,” said one procurement official. “there is a lot of activity going on and the market will deepen in quantity and quality in the years ahead.” Ekşi from C4Defence.com said: “Twenty-two local bidders in a relatively small drone competition is a sign that the market, infant by age, will flourish soon.” https://www.defensenews.com/global/europe/2018/11/07/companies-line-up-to-deliver-turkey-hundreds-of-micro-drones
