Despite US lawmakers' concerns that Egypt is lagging on democratic reforms, Egypt remains one of Washington's closest security allies in the region.
Relations had cooled after former President Mohamed Morsi of the Muslim Brotherhood was overthrown by the military in 2013 after mass protests against his rule.
However, ties with former general Abdel Fattah el-Sisi, who was later elected as president, have steadily improved.
US President Barack Obama, in late March, lifted a hold on a supply of arms to Cairo, authorising deliveries of US weapons valued at more than $1.3bn.
At the time he directed the release of 12 Lockheed Martin F-16 aircraft, 20 Boeing Harpoon missiles, and up to 125 M1A1 Abrams tank kits made by General Dynamics.
Last month, Washington delivered two navy vessels to Egypt, doubling Cairo's total fleet of Fast Missile Craft to four.
US Secretary of State John Kerry will be in Egypt on Sunday to hold a "strategic dialogue", which last took place between the two countries in December 2009.
