On 7 July 2007, International Launch Services launched the first Proton-M Enhanced rocket (also called M+), which carried the DirecTV-10 satellite into orbit. This was the 326th launch of a Proton, the 16th Proton-M/Briz-M launch, and the 41st Proton launch to be conducted by ILS. [13]
The initial version of Proton M, could launch 3–3.2 tonnes (6,600–7,100 lb) into geostationary orbit or 5.5 tonnes (12,000 lb) into a geostationary transfer orbit. It could place up to 22 tonnes (49,000 lb) in low Earth orbit with a 51.6-degree inclination, the orbit of the International Space Station (ISS).
This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets.
A Proton with a Briz-M can place a 4,385 kg satellite, such as an A2100AX, into a target orbit with an apogee of 35,786 km, a perigee of 7,030 km, and an inclination of 17.3°. [ 9 ] [ 10 ] Maximum lift capability of the Briz-M stage is 5,645 kg to geosynchronous transfer orbit with a 1,500 m/s residual velocity to GSO. [ 6 ]
As of 13 March 2023, rockets of the UR-500 / Proton family have accumulated 430 launches since 1965, 382 of which were successful, yielding an 88.8% success rate.

As of September 2015, 3 Proton-M/Blok DM-03 have been launched, of which 2 have failed. In the 2010 failure, the rocket was too heavy to reach orbit and reentered the atmosphere during a coast phase between the end of third stage flight and the beginning of the Blok DM-03's first burn, whilst the 2013 flight failed after the rocket went out of ...
