DOD budget pushing house cleaning pivot to leading-edge technologies: out with the old and in with the new

Budget has $9.8 billion for cyber security and cyber warfare; $3.2 billion for hypersonics; and $800 million for artificial intelligence (AI) research.

THE MIL & AERO COMMENTARY – The 2021 U.S. Department of Defense (DOD) budget proposal is out, and it looks like several years of consistent growth driven by the Trump Administration may be leveling off. A closer look, however, may indicate a pivot to new leading-edge technologies and away from legacy systems.

DOD leaders in their fiscal 2021 budget request to Congress, which was released last month, are asking for $705.4 billion, which is down about 1 percent from this year's level of $712.6 billion. Before you conclude that the Pentagon budget has turned flat, however, take a look at where the money's going.

First, the bad news: procurement. This is where big-ticket items like aircraft, combat vehicles, and ships get funding. The DOD's procurement budget request for 2021 is $136.9 billion, down nearly 7 percent from this year's level of $147.1 billion.

Contained in the DOD budget for procurement, moreover, are aggressive cuts to legacy weapons systems. The U.S. Air Force, for example, will retire 24 RQ-4 Block 20 and Block 30 Global Hawk Battlefield Airborne Communications Node (BACN) unmanned aerial vehicles (UAVs) and Block 30 multi-intelligence aircraft UAVs next year.

The U.S. Navy, meanwhile, will retire four Ticonderoga-class missile cruisers. The U.S. Army plans to eliminate 13 programs involving munitions, fires, protection, sustainment, mobility, mission command, and cyber programs that no longer are priorities. Additional cuts are expected.

Next year the Navy plans no additional purchases of P-8A Poseidon maritime patrol aircraft; the MQ-4 Triton long-range maritime patrol UAV; or the MQ-25 Stingray UAV.

The counterweight to these procurement cuts, however, is in the DOD's budget for research, development, test, and evaluation (RDT&E). As procurement spending is going down, the research budget is headed in the other direction. The Pentagon is asking for $106.6 billion, which is up about 1 percent from this year's research budget of $106.6 billion. Revealing is money is going.

The DOD next year plans to spend $9.8 billion for cyber security and cyber warfare -- up 81 percent from $5.4 billion this year; $3.2 billion for hypersonics; $1.5 billion for military microelectronics and 5G networking; and $800 million for artificial intelligence (AI) research.

The Pentagon hypersonics budget will pay for research and development initiatives to develop the Army Long-Range Hypersonic Weapon; Navy Conventional Prompt Strike (CPS); and Air Force Advanced Rapid Response Weapon (ARRW).

Research money also would include $1.1 billion for the Navy's next-generation frigate; $4.4 billion for the future Columbia-class ballistic missile submarine; and $464 million for two Large Unmanned Surface Vessels.

The U.S. Defense Advanced Research Projects Agency (DARPA) is asking for $3.6 billion in 2021, a 3 percent increase from the $3.5 billion the agency received this year. DARPA has asked for $322.7 million for electronics research in 2021 -- a 1.7 increase from the 317.2 million the agency received this year. For sensors research, DARPA is asking for $200.2 million in 2021 -- a 26 percent increase over the $158.9 million the agency received this year.

So, in short, it sounds like out with the old, and in with the new at the Pentagon. Four Navy cruisers that are at least 30 years ago are heading for retirement. Large, slow, and vulnerable Global Hawk UAVs are to be taken out of service, and Army programs no longer relevant amid today's global threats will be taken off the board.

At the same time, enabling technologies considered crucial for today's military needs are on the upswing: hypersonic munitions and aircraft, cyber security and cyber warfare, 5G networking, and artificial intelligence.

Perhaps the DOD has been due for a house cleaning like this for a while. Getting rid of obsolescent weapons systems makes sense because they're past the point of diminishing returns. Pumping more money into technologies for tomorrow's battlefield makes sense, too. These kinds of realignments are painful, yet essential.
