According to the Military Times, data from the Defense Health Agency indicate the U.S. Department of Defense spent $41.6 million on Viagra and $84.24 million total on drugs for erectile dysfunction in 2014.

Since 2011, the bill for covering drugs like Viagra, Cialis and Levitra for active and retired military personnel and eligible family members totalled $294 million — nearly as much as four U.S. Air Force F-35 Joint Strike Fighters, says the Military Times.

The DoD first began covering the cost of Viagra prescriptions in 2012, and currently another seven types of erectile dysfunction medications are paid for under the federal agency’s health plan. Of the 1.18 million prescriptions filled in 2014, 905,083 were for Viagra, at a cost of $41.6 million. Cialis was the second most commonly prescribed ED drug, with 185,841 prescriptions totaling $22.82 million. Revatio, the priciest ED drug, was prescribed the least with 1,699 prescriptions in 2014 for a total cost of $2.24 million.
