Sailors and Marines deployed for more than 220 consecutive days as a result of normal peacetime requirements will be paid Hardship Duty Pay – Tempo (HDP-T).

Effective Sept. 17, Sailors and Marines alike “will receive HDP-T on a prorated daily basis of $16.50, not to exceed a monthly rate of $495,” according to a Navy release.

For units currently deployed, like the USS Bataan Amphibious Ready Group and George H. W. Bush Strike Group consecutive days prior to Sept. 17 will count when determining eligibility for payment. Payment will not be made for deployments that concluded before Sept. 17.

Military pay systems are being updated to handle payment of HDP-T; expected date of completion is by the end of the year. Sailors and Marines eligible for HDP-T as of Sept. 17 will accrue the pay and see it in their pay checks once the system update is complete.

“The Navy and Marine Corps’ unique ability to provide and maintain a global presence is made possible by the hard work of our Sailors and Marines,” Secretary of the Navy Ray Mabus said in a statement.

“For some time now, these men and women have met the significant demand for our forces without waver,” he added. “As the need for our presence continues, Hardship Duty Pay – Tempo (HDP-T) is an important effort to further compensate our Sailors and Marines for their willingness to take on extended deployments and for the frontline role they continue to play in keeping our nation, and our world, safe.”
