The Defense Department has released new guidance for the continuation of military operations and other activities amid a government shutdown.

The document published Thursday states that the shutdown will not affect government contractors that provide services under a fully funded contract the department awarded prior to the expiration of federal funding.

New contracts such as task orders, contract renewals and exercise of options that do not support “excepted activities” may not be carried out under the shutdown.

“In cases where additional funding is required and/or oversight, engagement, or inspection by federal employees who have been furloughed is critical to successful performance under the contract and the contract is not required to support an excepted activity, the issuance of stop work order or the termination of the contract may be required,” according to the document.

Defense Secretary James Mattis wrote in a Friday memo that DoD will continue to carry out daily operations worldwide during a government shutdown, DoD News reported Saturday.

The shutdown resulted after Congress failed to pass another stopgap bill Friday.

“Ships and submarines will remain at sea, our aircraft will continue to fly and our warfighters will continue to pursue terrorists throughout the Middle East, Africa and South Asia,” Mattis noted.

“While training for reservists must be curtailed, active forces will stay at their posts adapting their training to achieve the least negative impact on our readiness to fight,” he added.

Chiefs from the NATO Military Committee have discussed efforts to address security and stability challenges in the southern part of Europe during a meeting in Brussels, Belgium, DoD News reported Wednesday.

Czech Army General Petr Pavel, chairman of the NATO military committee, said the chiefs and representatives from partner nations conversed about the Resolute Support mission in Afghanistan, operations against the Islamic State militant group in Iraq and Syria as well as the situations in Georgia and Ukraine.

“We discussed the strategic, operational and political context in and around Afghanistan, as well as our main effort to train, assist and advise the Afghan security forces and institutions,” said Pavel.

“We deliberated how NATO could adapt our current activity within our training and capacity-building initiative in Iraq, upon request by the Iraqi authorities and taking into consideration the importance of local ownership and buy-in.”

U.S. Army Gen. Curtis Scaparrotti, NATO supreme allied commander for Europe, noted alliance members have responded to the situation in Georgia and Ukraine and performed activities such as the Very High Readiness Joint Task Force and Baltic Air Policing enhanced air policing and ongoing maritime operations.

Michael Griffin, the White House’s nominee for defense undersecretary for research and engineering, has expressed his support to the Defense Innovation Unit Experimental and the Pentagon’s strategic capabilities office during his Senate confirmation hearing, Federal News Radio reported Thursday.

Griffin, former NASA administrator, told Senate Armed Services Committee members Thursday that DIUx and SCO work to facilitate the acquisition process, promote innovation and encourage companies to collaborate with DoD.

He said he intends to reform the Pentagon’s weapons procurement process and address the “valley of death” between technology development and production once confirmed.

“It’s very difficult to set aside and fence money specifically for transition, so one of the things I would like to do if I’m confirmed, is I would like to more formalize the role of transition offices,” he told lawmakers.

“If we think we have a problem with transition… I think the first step to solving it is to put someone in charge of it and give them that task,” he added.
