Rank insignia wear
On the service dress uniform metal rank is worn on the epaulets. On the OCP uniform, the Space Force's combat utility uniform, embroidered navy blue rank is worn on an OCP patch on the center of the chest.
The creation of the Space Force marked the first time since the 1947 creation of the Air Force that a new branch was created. This created an interest in the rank structure and insignia. In February 2020, it was announced that the Space Force would ask military space professionals for opinions on ranks.
Eighty-six graduates of the United States Air Force Academy class of 2020 commissioned directly into the USSF, becoming the service's first new officers and second lieutenants. On July 28, 2020, four general officers from the Air Force were nominated to transfer to the Space Force in their current grade of major general, and then be promoted to lieutenant general. On August 6, 2020, a number of Air Force officers are being transferred to the Space Force in the ranks of major, lieutenant colonel and colonel.  On September 1, 2020, the Air Force transferred 2410 active-duty airmen to the Space Force to become enlisted space professionals. The space professionals were all transferred to the Space Force in their current enlisted ranks.
The Space Force was set to announce its new rank structure in late August 2020 but decided to delay it temporarily, as a proposed amendment included in the United States House of Representatives's version of the 2021 National Defense Authorization Act would require the Space Force to adopt a rank structure based on that of the United States Navy for its officers and enlisted space professionals. The Space Force will wait until after the 2021 NDAA is passed, before moving forward with their permanent rank structure. Until then, all members of the Space Force currently retain their respective grade and rank carried over from the Air Force. On November 16, 2020, the Senate passed the House of Representative's version of the NDAA, but attached an amendment which would remove the clause requiring the Space Force to adopt naval ranks, and sent it back to the House for consideration. The House unanimously disagreed with the Senate's amendment and sent the amended bill back to their armed services committee on November 18, for consideration of passage. The final version of the National Defense Authorization Act removed any requirement for the Space Force to adopt naval ranks. The official rank structure became effective on 1 February 2021, which includes the rank of specialist being used for paygrades E-1 to E-4 for the first time since the Army discontinued its use of multiple specialist ranks in 1985. It has also been confirmed that the Space Force will continue to use the Air Force enlisted rank design until a majority of guardian feedback is collected for the creation of its own unique design.

The Senate amendment contained no similar provision. The House recedes.
