The Trump administration has objected to a provision under the Senate’s proposed fiscal 2018 defense policy bill that would restrict all funds for U.S. Army battlefield network development efforts, C4ISRNET reported Saturday.

The White House said in a statement published Friday that implementing funding limitations to the Warfighter Information Network-Tactical program would affect the Army’s on-the-move communications, intelligence analysis and air and missile defense operations.

The Senate’s proposed National Defense Authorization Act for 2018 does not include President Donald Trump’s $420 million budget request for the General Dynamics-led WIN-T program.

Army Chief of Staff Gen. Mark Milley voiced concerns over whether WIN-T can function as intended and ordered the service branch to review the program.

Several House and Senate lawmakers previously urged Milley to consider the implementation of a new procurement strategy that would accelerate fielding of the network.

The upper chamber aims to take up NDAA this week.

Ann Stefanek, a spokeswoman for the U.S. Air Force, has said the service branch has been in talks with White House officials to reduce the cost of the next presidential planes and one of the cost-saving plans is to forgo the aircraft’s aerial-refueling capability, Defense One reported Friday.

Cost-cutting plans for the new aircraft came a month after the service branch awarded Boeing a contract modification to convert a pair of 747-8 aircraft into Air Force One planes.

The 747-8 aircraft variant is designed to fly approximately 1,800 nautical miles farther than the aging presidential planes, according to a copy of Boeing CEO Dennis Muilenburg’s December 2016 briefing obtained by Defense One.

Stefanek told the publication in an email the future Air Force Ones will be equipped with commercial interior furnishings that include an environmental control system for cooling and filtering cabin air.

The report said the service also has begun to negotiate prices for seats and other aircraft components with Boeing and subcontractors in order to lower the aircraft’s final procurement price that would not be disclosed until the summer of 2018.

Vice Adm. Mathias Winter, head of the F-35 joint program office, has said he forecasts that another continuing resolution could slow down the development and testing of F-35 fighter aircraft beginning April 2018, Defense News reported.

Winter told reporters at a Defense News-hosted conference the F-35 program will remain on track until December even under the current stopgap funding measure, but he noted the program would need to request additional funds in January to maintain the pace of activities.

“Right now, based upon the current plan, we should see no major impact until the April time frame,” Winter said.

“We’ll be on track as we’re executing through December. In January, we’ll see where we are.”

Rep. Mac Thornberry (R-Texas) said at the same forum that Congress will likely pass a continuing resolution to fund government operations until December.

The Government Accountability Office has stated that the Defense Department must continue efforts to mitigate issues related to persistent maintenance, training and readiness of the U.S. Navy fleet.

GAO said in a report published Thursday that the Navy currently faces issues related to the manning, training and maintenance of its fleet, issues that are hindering plans to grow the naval arsenal by up to 30 percent.

The government watchdog agency listed points of concern regarding the naval fleet covering the potential degrading ship readiness of vessels deployed overseas and the lack of a capacity to perform maintenance operations within a given schedule.

The report added that the Navy’s move to reduce crew sizes may also lead to safety risks and sailors being overworked.

GAO has made recommendations on the assessment of risks related to overseas basing, planning and sustained management, sailor workload and ship crew sizing strategies.
