Leaders of Group of Seven member states have issued a joint declaration that calls for social networking sites and internet companies to stem the spread of terror propaganda, the Associated Press reported Friday.

State leaders signed the declaration Friday during the G7 Summit in Sicily, Italy, days after the Islamic State militant group-related suicide bombing attack in Manchester, England, that resulted in the death of 22 individuals.

Heads of the U.S., Japan, U.K., Canada, Germany, Italy and France jointly urged industry to develop and share new technology platforms designed to detect and remove content that promotes online extremism and violence, The Hill reported Friday.

Facebook has said it has collaborated with other groups to eliminate extremism-related content, while Twitter suspended in February 2016 125,000 accounts that promote terrorism, the report added.

The U.S. Army’s fiscal year 2018 budget proposal indicates a possible four-year delay in the initial operational capability of the service branch’s anti-missile command-and-control platform, Defense News reported Thursday.

The service now expects to achieve IOC for the Northrop Grumman-built Integrated Air and Missile Defense Battle Command System by the third quarter of FY 2022 compared with the FY 2017 budget request in which the Army anticipated to meet IOC by the third quarter of FY 2018.

The service branch’s FY 2018 proposal also showed an increase of more than $500 million in research, development, test and evaluation funds compared with the budget request for fiscal 2017.

Dan O’Boyle, a spokesman for the Army, told Defense News in a statement issued Thursday the additional funds and revised schedule seek to facilitate integration with the Patriot software’s latest version and buy time for development, analysis and testing phases to demonstrate software functionalities.

IBCS is a component of the service’s Integrated Air and Missile Defense System designed to replace the Patriot platform and is built to be interoperable with combat platforms such as the Indirect Fire Protection Capability system that works against artillery and rockets, the report added.

The Defense Department‘s budget request will allocate $259 million to accelerate the development of a kill vehicle for the U.S. military to intercept multiple enemy warheads, Defense One reported Friday.

The budget request will fund a new development phase for the Multi-Object Kill Vehicle and shorten the program’s projected completion date by five years, according to the report.

An unnamed official from the Missile Defense Agency told the publication that MDA seeks to have a demonstrated MOKV platform by 2025 through accelerated risk reduction and product development phases.

The official added the decision is “not in response to any specific intelligence, but to stay ahead of potential future threats,” the report stated.

Gen. Stephen Wilson, vice chief of staff at the U.S. Air Force, has said the military service’s leaders believe the branch must have funding stability to provide airmen with equipment needed to modernize the nuclear triad.

He discussed the service branch’s plans to boost the nuclear triad’s flexibility, responsiveness, survivability and visibility at a Mitchell Institute-hosted breakfast event at the Capitol Hill Club in Washington, the Air Force said Friday.

Wilson noted that the Air Force plans to replace ground-based strategic deterrent missiles with the Minuteman III and update long-range standoff missiles to make the system compatible with nuclear-capable bombers.

The service branch maintains two legs of the nuclear triad that includes aircraft designed to carry nuclear weapons; more than 400 intercontinental ballistic missiles; nearly 30,000 airmen; and 75 percent of the nuclear command, control and communications system built to connect the U.S. president with senior military leaders.

President Donald Trump’s proposed a $183 billion budget for the Air Force would cover procurement, operations and maintenance and research, development, testing and evaluation programs in fiscal 2018.

President Donald Trump has urged NATO member countries to meet commitments to spend 2 percent of their gross domestic product on defense, DoD News reported Thursday.

Trump said at the NATO headquarters in Brussels, Belgium that the 2 percent commitment is the “bare minimum” for addressing current threats and is not enough to meet modernization, readiness and force size needs.

“If all NATO members had spent just 2 percent of their GDP on defense last year, we would have had another $119 billion for our collective defense and for the financing of additional NATO reserves,” he added.

Trump noted that 23 of 28 NATO members have yet to meet their defense spending commitments.

The president stated NATO must increase its focus on terrorism, immigration and threats from Russia as well as nations along NATO’s eastern and southern borders.
