A potential transfer of U.S. Army Stryker vehicles to Poland involves old equipment and isn’t tied to military force posture plans in Europe, U.S. Army Europe and Africa said.

The Navy’s oldest aircraft carrier and its crew will be home for Christmas after what is expected to be the final deployment of its 50 years in service.

The Air Force has operated the KC-46A since 2022 and expects the aircraft to remain in service into the 2070s. It can carry up to 212,299 pounds of fuel and also be used for cargo, troop transport and medical evacuation.

Lt. Col. Michael Trott will be the first to fly the T-7A Red Hawk training aircraft to San Antonio, where his squadron will begin the final sprint to integrating the plane as the primary trainer for Air Force pilots.

The four investigations focused on lost aircraft and a tow tractor, a collision with a merchant vessel and a case of friendly fire involving the carrier and its strike group. The collision in February could have been “catastrophic.”

An unidentified Marine assigned to I Marine Expeditionary Force died from injuries sustained in a tactical vehicle “mishap” at Marine Corps Base Camp Pendleton in Southern California, the service said.

The Polar Star is making the trip as part of Operation Deep Freeze, the annual resupply of U.S. outposts under the U.S. Antarctic Program, led by the National Science Foundation.

The pilot is in stable condition and receiving follow-on care, the Air Force said.

On what is likely the final deployment of its 50-year Navy career, the Nimitz over the past eight months patrolled the Indo-Pacific region and was diverted for several weeks to the Arabian Sea amid heightened tensions between Israel and Iran.

The Navy said late Tuesday it plans to cancel the bulk of the $22 billion Constellation-class guided-missile frigate program dogged by delays and cost overruns.
