GOP defense hawks plan to offer an alternative spending plan during Wednesday's markup to boost the bill's price tag by approximately $25 billion. The proposal would put the House version of the National Defense Authorization Act on par with the Senate bill. The amendment would add $9.8 billion to weapons procurement accounts, including money for four more Navy ships, more planes and helicopters for the Navy, Marine Corps and National Guard, and upgraded Army combat vehicles. It would also pour an extra $5.2 billion into research and development efforts, including emerging technologies and cybersecurity and artificial intelligence.
