This included $67.9 billion to be designated by Congress and the President as funding for Overseas Contingency Operations (OCO) and $599.4 billion for DOD's base budget, comprising all operations not designated as OCO. OCO-designated funding is related to current operations in Afghanistan and Syria, but includes other activities that Congress and the President so-designate. As enacted, H.R. 114-113), the FY2019 act provides an increase of 2.3%. A House-Senate conference committee reported a version of the bill on September 13, 2018. The Senate approved the conference report on September 18 by a vote of 93-7 and the House did likewise on September 26 by a vote of 361-61. President Donald J. Trump signed the bill into law ( P.L. 115-245 ) on September 28, 2018. The total amount requested for DOD that falls within the scope of the annual defense appropriations bill and amounts provided in P.L. 115-245 as enacted are relatively close. While the act makes hundreds of additions and cuts to the funding requested for particular items, three broad themes all push the act's procurement total upward: $2.48 billion is added to buy aircraft and other equipment for National Guard and reserve forces; $2.31 billion is added to fully fund or acquire major components for additional six ships (see Table 9 ); and $2.13 billion is added to the $8.49 billion requested for procurement of F-35 Joint Strike Fighters (see Table 10 ). The caps on defense-related spending apply to discretionary funding for DOD and for defense-related activities by other agencies, comprising the national defense budget function which is designated budget function 050 . Congress has raised the annual spending caps repeatedly, most recently with the Bipartisan Budget Act of 2018 (P.L. Appropriations Overview

		Military Personnel

The law funds the Administration's proposal to increase the size of the armed forces by 15,600 personnel in the active components – with nearly half of that increase destined for the Navy – and by a total of 800 members of the Air Force Reserve and Air National Guard.
The FY2019 Department of Defense Appropriations Act, enacted as Division A of P.L. 115-245 , provides $667.3 billion in new budget authority to fund all activities of the Department of Defense (DOD) except for the construction of military facilities and the operation of military family housing complexes.
While the total amount appropriated for DOD for FY2019 was nearly equal to the Administration's request, the act provides more funding than requested for dozens of weapons acquisition programs, with the gross increase exceeding $10 billion. Those additions are offset by hundreds of reductions made elsewhere within the budget request.
In effect, these reductions allowed Congress to add billions of dollars to the Administration's DOD budget request without exceeding the cap on defense spending that arose from the Bipartisan Budget Act of 2018 ( P.L. 115-123 ). That cap applies to discretionary appropriations for DOD's base budget —that is, appropriations designated by Congress and the President as funding for emergencies or for Overseas Contingency Operations (OCO). OCO activities include current operations in Afghanistan and Syria, and any other operations which are so designated by Congress and the President.

As enacted, H.R. 6157 funds the Administration's major defense initiatives, including an increase of 16,500 active-duty military personnel. Among the weapons procurement programs for which the bill provides substantial additions add to the amounts requested are the F-35 Joint Strike Fighter used by the Air Force, Navy, and Marine Corps (77 aircraft requested and 93 funded) and the Navy's Littoral Combat Ship (one requested and three funded).
