The USSF-12 mission for the U.S. Space Force’s Space Systems Command will launch a Wide-Field of View early warning missile detection satellite, developed by Millennium Space Systems and L3 Harris.

Atlas V: the workhorse of United Launch Alliance's rocket fleet.

The rocket is a mix of Russian and American technology, using the Russian RD-180 as the rocket's first stage engine, and is one of the most versatile rockets in the world with 20 possible configurations -- though only 10 have flown.

Developed in the mid-to-late-1990s, it is the fifth and last major version of the veteran Atlas rocket, which began flying in 1957.

Lockheed Martin designed and built Atlas V as part of the U.S. government's 1994 initiative to create an Evolved Expendable Launch Vehicle (EELV) program for national security missions.

The two companies with EELV rockets -- Lockheed Martin with Atlas V and Boeing with Delta IV -- merged in 2006, creating an effective U.S. market monopoly with United Launch Alliance (ULA).

For years, the U.S. government paid ULA over $800 million annually -- not for rockets or launches but for ULA to maintain their facilities to be ready to launch EELV missions.

Therefore, pricing of the Atlas V has varied greatly over the years, with a basic Atlas V 401 (no boosters and a single-engine second stage) costing anywhere from the high-$90 millions to $163 million USD in the 2000s and early 2010s.

Sweeping price and cost-per-launch figure reductions have occurred since SpaceX began directly competing against ULA in the 2010s.

The Atlas V’s 541 variant costs a minimum of $145 million USD.

While not the cheapest rocket on the market, the Atlas V's safety and success are unparalleled -- with a 100% mission success rating.

Atlas V 541

This mission will use the Atlas V 541 variant - with a five-meter payload fairing (5), four side-mounted solid rocket boosters (4), and a single engine Centaur upper stage (1).

Of its flights to date, the Atlas V 541's most prominent flights have included NASA's Curiosity Rover on November 26th, 2011, The Mars Perseverence Rover on July 30th, 2020 as well as multiple NRO and GOES satellite launches.

Space Launch Complex 41 (SLC-41) is a significant launch site located at Cape Canaveral Space Force Station (CCSFS) in Florida. Originally built in the 1960s, SLC-41 was designed to support the Titan III and Titan IV rocket programs. Throughout its history, the pad has been used for various missions, including the deployment of military and reconnaissance satellites. A notable launch from SLC-41 was the Cassini spacecraft mission, which began its journey to Saturn in 1997.

In the early 2000s, SLC-41 was repurposed to support the Atlas V rocket, operated by United Launch Alliance (ULA). This transition involved extensive upgrades to the pad’s infrastructure and the installation of new ground support equipment to accommodate the Atlas V. These modifications ensured that SLC-41 could meet the requirements of modern space missions.

Under ULA’s management, SLC-41 has hosted a range of important launches, including the Mars Science Laboratory mission, which successfully landed the Curiosity rover on Mars in August 2012, and the launch of GPS III satellites, enhancing global positioning capabilities. The pad has also supported Boeing's CST-100 Starliner capsule, which is part of NASA’s Commercial Crew Program. The Starliner capsule, designed to transport astronauts to and from the International Space Station, has been launched from SLC-41 to support crewed missions.

Looking to the future, SLC-41 is set to support ULA’s Vulcan Centaur rocket. The Vulcan Centaur is intended to replace the Atlas V and Delta IV rockets, marking a new era in ULA’s launch capabilities with enhanced performance and cost-efficiency. The pad’s infrastructure will be further updated to accommodate this next-generation rocket.
