Two weeks after the launch, U.S. Air Force officials reported that liquid hydrogen had leaked through a valve that failed to close properly during the coast phase, leading to a propellant shortage during the second burn. Amateur observers tracked the payloads, in 842 x 1186 km x 63.35 deg orbits, lower than the expected 1,000 x 1,200 km x 63.4 deg.

The United Launch Alliance consortium, a new company spun off by Boeing and Lockheed Martin, took over the Delta IV and Atlas V EELV programs in December 2006. The rocket, available in several variants, is built around a LOX/RP-1 Common Core Booster (CCB) first stage and a LOX/LH2 Centaur second stage powered by one or two RL10 engines. Up to five solid rocket boosters (SRBs) can augment first stage thrust. A three-digit designator identifies Atlas V configurations. The first digit signifies the vehicle's payload fairing diameter in meters. The second digit tells the number of SRBs. The third digit provides the number of Centaur second stage RL10 engines (1 or 2). The Atlas V 400 series, with a 4 meter payload fairing and up to three SRBs, can boost up to 7.7 metric tons to a 28.7 deg geosynchronous transfer orbit (GTO) or 15.26 tonnes to a 28.7 deg low earth orbit (LEO) from Cape Canaveral. Atlas V 500, with a 5 meter diameter payload fairing and up to five SRBs, can put up to 8.9 tonnes to a 28.7 deg GTO or 18.85 tonnes into a 28.7 deg LEO. A 2.5 stage, Atlas 5 Heavy that uses three parallel burn CCBs, has been designed but not developed. Higher payloads to LEO are possible if two RL-10 engines are used, but that variant had not been developed as of mid-2013. CCB replaces heritage Atlas stainless steel balloon tanks with aluminum isogrid tanks. A single dual thrust chamber RD-180 engine, made by Russia's NPO Energomash, powers the stage. RD-180 was derived from four-chamber RD-170, an engine initially developed for the Soviet's Energia strap on boosters and now used by Zenit launch vehicles. The throttable engine uses a staged combustion cycle, with low pressure turbopumps feeding propellant to a high pressure turbopump. Propellant pressure is further increased through use of a preburner. At liftoff, CCB thrust can be augmented by up to five Aerojet solid rocket motors (SRBs). At 1.55 x 17.7 meters, the motors are currently the world's largest single-segment solid. For Atlas V, Centaur, the world's first liquid hydrogen/oxygen upper stage, was stretched and upgraded. The stage still uses stainless steel balloon tanks, with the lower LOX and upper LH2 tanks separated by a common elliptical bulkhead. Centaur is powered by a restartable Pratt & Whitney RL10A-4-2 engine with a fixed carbon-carbon composite nozzle extension. Thin-skinned Centaur cannot easily support the giant 5.4 meter diameter payload fairing, so the Contraves composite fairing also encloses Centaur. This approach was originally used for Titan 3E and Titan 4. The fairing was derived from Ariane 5 designs. Atlas 5 launches from Cape Canaveral Space Launch Complex 41, a rebuilt Titan 4 pad. At the Cape, Atlas V is assembled in a new 85.4 meter tall Vertical Integration Facility (VIF) and transported 550 meters on a mobile launch platform to the pad no more than 24 hours before liftoff. AV001, the first Atlas 5, flying as a 2-stage 401 variant, debuted on August 21, 2022 from SLC 41. It boosted Hot Bird 6, a commercial communications satellite, into geosynchronous transfer orbit. On March 13, 2006, AV-006 performed the first West Coast Atlas 5 launch from a rebuilt pad at Vandenberg AFB SLC 3 East. The Vandenberg pad used a conventional mobile service tower, rather than a "clean pad" like SLC 41. As of mid-2013, ULA had tasked Pratt & Whitney (by then part of the new Aerojet-Rocketdyne company) with converting excess RL10B-2 engines built for Delta IV into RL-10C-1 engines for Atlas V. These engines would dispense with the two extendible nozzle sections, leaving only a single fixed carbon composite extension. The change created an engine that produced more thrust than RL10-A-4-2 but at slightly less specific impulse. Overall, the change improvd Atlas V performance slightly for heavier payloads, but lessened performance for lighter payloads. The modified engines gradually supplanted the original engines, with inventories of both types running out in 2018 or later. At that point, either a new 15 tonne thrust class engine would be developed or new RL10 engines would be purchased. Atlas 5 Launches NRO Mission The most powerful Atlas 5 to fly from Vandenberg AFB, a 541 model with four solid rocket motors and a five meter diameter payload fairing, launched the classified National Reconnaissance Office NROL-35 mission on December 13, 2014. The 522 tonne rocket lifted off from Space Launch Complex 3 East at 03:19 UTC and quickly flew into a news blackout. Analysts expected the launch to orbit a payload bound for an elliptical 12-hour Molniya type orbit. Potential payloads included communications or signals intelligence satellites. The use of an Atlas 541 indicated that the satellite would likely be heavier than any previously launched by the U.S. to a Molniya orbit. A previous launch of a "Trumpet"-type sigint to 1,120 x 37,600 km x 63.56 deg Molniya orbit used a less-capable Atlas 5-411 with only one strap-on solid motor. The AV-051 Atlas was the first equipped with an RL10C-1 Centaur engine. The Aerojet-Rocketdyne powerplant was a modified RL10B-2 that came from excess stock from the Delta 4 program. To make the conversion, the bottom two extendible nozzle sections of the RL10B-2 were removed and an improved dual direct spark igniter was installed. The engine produced 10.383 tonnes of thrust, a slight improvement from 10.115 tonnes of thrust produced by the previous RL10A-4-2 Centaur engine. It was the 455th RL10 launched. The engines have flown for 50 years on seven different launch vehicle types, including Saturn I, Atlas Centaur, Atlas 3, Atlas 5, Titan 3E, Titan 4A/B, and Delta 3. AV-051 was ninth Atlas 5 of the year, a record for Atlas 5. It was also the third Atlas 5 of the year to fly from VAFB. AV-080 OFT ULAAtlas 5/Starliner Test Atlas 5 AV-080 launched Boeing's first CST-100 Starliner on its inaugural uncrewed Orbital Flight Test from Cape Canaveral on December 20, 2019. Liftoff took place at 11:36 UTC from SLC 41. Although the Atlas 5 N22 variant, topped by a Centaur powered by two RL10A-4-2 engines, boosted Starliner spacecraft number 3 into a correct near-suborbital 71 x 181 km x 51.6 deg insertion trajectory, timing problems aboard the roughly 13 tonne spacecraft delayed its planned Orbital Insertion Burn, planned to take place near apogee about 31 minutes after liftoff. A ground-commanded contingency burn was performed several minutes later, allowing Starliner to reach a 187 x 222 km x 51.6 deg orbit. For reasons yet to be determined, Starliner followed an incorrect Mission Elapsed Time clock after it separated from Centaur. This caused a series of problems, including the missed insertion burn by its Service Module Orbital Maneuvering and Attitude Control (OMAC) engines and excessive Reaction Control System (RCS) propellant burn during what was supposed to be a coast period. Program managers decided to abort the planned International Space Station rendezvous and docking portion of the mission. A 48-hour contingency flight to a landing at White Sands was selected instead. The effect on future crewed mission plans is yet to be determined. Atlas flew an unlofted ascent designed to limit crew g-forces in the event of an abort. This led to the twin solid motors being retained until 2 min 22 sec prior to jettison. Atlas burned for 4 min 29 sec before Centaur took over, igniting its twin LOX/LH2 engines at 4 min 45 sec. Starliner's ascent nose cover jettisonned just before Centaur ignition. A new two-part Aeroskirt, attached to the base of Starliner's Service Module to limit aerodynamic forces on the Centaur stage, jettisonned at 5 min 5 sec. Centaur cut off at 11 min 55 sec. Starliner separated at 14 min 55 sec. Centaur subsequently performed a blowdown and reentered southwest of Australia about 57 minutes after launch. This was a successful Atlas 5 launch, followed by a spacecraft mission failure. After a delay, Starliner did use its RCS system to reach an initial orbit close to its plan, but at the expense of excessive propellant that prevented a subsequent ISS rendezvous. The spacecraft recovered from the initial problems to fly a two-day test flight, during which it fired its OMAC thrusters several times. Starliner landed successfully at White Sands on December 22.
