President Donald Trump has decided to eliminate a weight limit on warheads added to South Korea’s missile systems in response to a nuclear missile test launch from North Korea, Reuters reported Monday.

The current missile pact between U.S. and South Korea limits the weight of the latter country’s warheads to 1,100 pounds per unit at a flight range of up to 497 miles.

Trump also issued a conceptual approval that provides an option for South Korea to purchase billions of dollars worth of weapons from the U.S. during his meeting with South Korean President Moon Jae-in, the report noted.

Stars and Stripes reported Monday that South Korea also wants to install four more launchers for the Terminal High Altitude Area Defense missile defense system.

South Korea’s ministry of national defense said the additional deployment will help the country counter potential nuclear threats from North Korea.

The U.S. Air Force has decided to remove the flight restriction on Lockheed Martin-built F-35A fighter aircraft at Luke Air Force Base in Arizona, Breaking Defense reported Wednesday.

The service branch imposed a flight ceiling of 25,000 feet in June in response to five incidents of hypoxia-like symptoms or oxygen deprivation experienced by F-35A pilots at Luke AFB.

“We have learned a lot over the past two months and while we have yet to identify a singular cause we have reduced potential causes for labored breathing, carbon monoxide ingestion, and refined our procedures and training,” Brig. Gen. Brook Leonard, 56th fighter wing commander at Luke, said in a statement.

“We will continue to closely monitor operations and work with the joint program office and the human performance wing on future improvements as we move forward building the future of airpower,” he added.

Military.com also reported the service branch has not yet identified the root cause of physiological incidents that occurred from May 2 through June 8.

Officials said the Air Force will begin the testing phase on the On-Board Oxygen Generating System aboard the affected aircraft to facilitate data analysis, the report added.

The U.S. Army has collaborated with industry to accelerate the production of the Lockheed Martin-built High Mobility Artillery Rocket System that works to home in on enemy targets at a range of up to 300 miles, Scout Warrior reported Monday.

“HIMARS production has resumed in the U.S. for the first time since mid-2013, creating a production capability critical for both U.S. and partner nations’ field artillery defense,” said Daniel O’Boyle, spokesman for program executive officer for missiles and space.

Boyle noted the re-establishment of a production line in the U.S. for HIMARS seeks to facilitate response to evolving conditions and requirements.

HIMARS is a long-range mobile rocket launcher mounted on an Army medium tactical vehicle designed to fire six guided multiple launch rockets and one MGM-140 Army Tactical Missile System.

The U.S. military has provided HIMARS to Iraq’s security forces to help counter the Islamic State militant organization.

The U.S. Air Force has accepted responsibility for the NATO Baltic air policing mission from Poland’s air force during a handover ceremony at the Sialuiai air base in Lithuania.

The Defense Department said Thursday that approximately 140 airmen and seven F-15C Eagle aircraft from the 493rd Expeditionary Fighter Squadron have been deployed to Lithuania to lead the Baltic air policing rotation mission until the end of the year.

DoD noted that the NATO air policing peacetime collective defense mission helps defend the integrity of alliance members’ respective airspace.

The Baltic air policing mission supports the NATO Smart Defense model wherein allied countries perform operations using shared capacities and coordinated efforts to boost mission success.

Gen. Tod Wolters, commander of the NATO Allied Air Command and the U.S. Air Forces in Europe, said that maintainers, mission supporters and operators from the U.S. will help defend the sovereign skies above Lithuania over the next four months.
