Hyundai Rotem readies Multipurpose Unmanned Ground Vehicle for delivery
by Dae Young Kim
South Korean defence and engineering prime Hyundai Rotem has been selected as the supplier of Multipurpose Unmanned Ground Vehicles (MUGVs) to the Republic of Korea Armed Forces.
Hyundai Rotem announced on 24 November that it had won a contract from the Defense Acquisition Program Administration (DAPA) to supply two MUGVs within six months under an accelerated acquisition scheme that aims to introduce new capabilities to the military. The company will also provide the associated support for the two vehicles.
MUGVs are two-tonne multirole platforms that can be fitted with a range of mission equipment depending on the user's requirements. The type can be used to perform combat reconnaissance in heavily contested battlefield environments to improve the firepower and survivability of troops.
The vehicle can also be used for supporting roles such as ammunition and expendable resupply, and casualty evacuation.
The MUGV will be derived from Hyundai Rotem's HR-Sherpa UGV, a 6×6 multirole dual-use platform that is 2.7 m in length, 1.7 m in width, and 0.9 m in height. It weighs 1.6 tonnes in its baseline configuration, and up to two tonnes when fully loaded. The company will also supply an in-house remote-control weapon system (RCWS) and plans to arm it with a 5.56 mm light machine gun.
The battery powered UGV is equipped with airless tyre technology and can turn on its axis. It is also equipped with a water-cooled battery and an integrated heat management system that supports long-distance driving in all-weather operations, and offers a claimed endurance of six hours when cruising at 5 km/h. It can also attain road and cross-country speeds of up to 40 km/h and 10 km/h, respectively.

Contract award for US Air Force’s Huey replacement helicopter at risk of delay until FY20
By: Valerie Insinna FARNBOROUGH, England — The U.S. Air Force's contract for a replacement to the UH-1N Huey helicopter could be delayed until fiscal 2020 unless Congress adds another $83.4 million to the program. According to a reprogramming request sent by the Defense Department to Congress, the UH-1N replacement effort is currently considered a “high risk” program due to a pre-award protest by competitor Sikorsky, a Lockheed Martin subsidiary, which was dismissed in May. The protest had temporarily put a hold source selection, deferring a contract planned for June to September. Current funds would expire at the end of the fiscal year on Sept. 30, meaning that if an award was further delayed it would take until FY20 to inject more money to continue on with the program, the request stated. Air Force Secretary Heather Wilson acknowledged in May that the contract could be awarded sometime this fall. “We're going to try and not let that slip too much because we know we need to get the Hueys replaced, but we did get a delay,” she had said. The Air Force's aging UH-1Ns are most well-known for the role they play defending nuclear missile sites, and it is the importance of this mission that has led to criticism from leaders in Congress and in the U.S. military — including U.S. Strategic Command head Gen. John Hyten — who have said the service needs to move more quickly to procure new helicopters. Three companies are competing for the Huey replacement award, with the first of a total of 84 new armored helicopters expected for delivery as early as 2020 — although if a contract is delayed until FY20 it seems likely that fielding will not be possible for another couple of years. Sikorsky is offering the HH-60U, a version of its UH-60 Black Hawk helicopter with modifications like a rescue hoist and electro-optical sensor. Sierra Nevada Corp. has pitched a modernized, life-extended version of used Army UH-60L aircraft that its calling “Sierra Force.” Meanwhile, Boeing and Leonardo are partnering on the MH-139, a militarized version of the Italian firm's civilian AW139 helicopter. Boeing submitted the final proposal for the aircraft Tuesday, it confirmed in a statement. “The Boeing MH-139 is capable, affordable, and ready to serve the United States Air Force's urgent UH-1N replacement needs,” the company said. "With a hot production line in Philadelphia, we are well-positioned to meet the USAF's delivery requirements for fielding this vital platform as soon as possible.” While the requirements for the helicopter were not made public, the Air Force has specified nine fully loaded troops without needing to be refueled for an endurance of at least 225 nautical miles. They also should be able to fly three hours while maintaining a 135-knot cruise speed. https://www.defensenews.com/air/2018/07/18/contract-award-for-air-forces-huey-replacement-helicopter-at-risk-of-delay-until-fy20
