Most expensive US military weapons and programs

With tax season fast approaching, many Americans are wondering where all the revenue collected by the federal government goes. A good portion of that money will be put toward national defense, which in the popular consciousness usually pertains to weapons and military programs, but in our present era also includes elements such as cybersecurity and climate change.
The national defense budget for 2023 was approved at $816.7 billion, an amount even higher than the request of $773 billion submitted in the budget proposed in March 2022. This is a marked increase over the $715 billion requested the previous year.
Expenditures as outlined within the Defense Department’s budget run the gamut from updating and modernizing existing military equipment to ensuring adequate pay for personnel, nuclear security, and missile defense, to disease response preparedness and cyberspace activities. Events over the last year, such as ongoing COVID-19 pandemic-related measures and tensions with nations such as China and Russia, have exacerbated what the federal government sees as a need for increased defense spending. Staying ahead of threats both foreign and domestic requires massive resources in a rapidly evolving world of technological, social, and environmental changes.
Using data from the Department of Defense’s Fiscal Year 2023 Budget Proposal as submitted on Mar. 28, 2022, Stacker ranked the most expensive military weapons and programs. This budget was signed into law on Dec. 23, 2022.

– 2023 Department of Defense budget investment: $3.1 billion
– Quantity proposed: not available
– Type of weapon or program: Climate Change
Climate change is not typically regarded as a threat that can be tackled through conventional defense, but the DOD has acknowledged that it will be destructive to existing defensive infrastructure and equipment. Installations in changing environments or areas with rising sea levels will experience accelerated structural degradation, equipment specific to certain environments will have to be altered, and there is a looming threat to the health of personnel. The Pentagon has obtained funds to enact a Climate Adaptation Plan to combat these natural threats to national security.
While tackling the climate crisis is seen by many as crucial work, critics often point out the extent to which the United States military itself contributes to climate change. A 2019 study from Brown University found that the DOD is the world’s largest institutional producer of greenhouse gases, contributing more emissions than many industrialized nations.
