Let's take a look at where does India's Agni-V stand in comparison with the ICBMs of other countries in the world:
Russia
R-36M (SS-18 Satan) missile is the world's longest range of ICBMs. Russia intends to replace the R-36 with a new heavy ICBM, the RS-28 Sarmat. Its throw-weight is 8,800 kg, making the Soviet R-36 the world's heaviest ICBM in comparison with the heaviest US ICBM (the retired LGM-118 Peacekeeper, that carried 10 warheads of 300 kt each) which had less than a half of this at 4,000 kg. It has a strike range of 16,000 kilometers.
Other active ICBMs include: UR-100N 15A30 / SS-19 Stiletto
RT-2PM Topol / 15Zh58 / SS-25 Sickle
RT-2PM2 Topol-M / SS-27 / RS12M1 / RS12M2
RS-24: MIRV-equipped.
R-29R SS-N-18 Stingray
R-29RK SS-N-18 Stingray Mod 2
R-29RL MIRV-equipped/SS-N-18 Stingray Mod 3
R-29RM MIRV-equipped/SS-N-23 Skiff
R-29RMU Sineva MIRV-equipped/SS-N-23 Sineva mode 2
R-29RMU2 MIRV-equipped/SS-N-23 Liner
RSM-56 Bulava MIRV-equipped/SS-NX-30
United States
The LGM-30 Minuteman is a land-based ICBM, in service with the Air Force Global Strike Command. As of 2016, the LGM-30G Minuteman III version[a] is the only land-based ICBM in service in the United States. It has an operational range of 13000 km but the exact range is classified.
Other ICBM include:
UGM-133 Trident II submarine-launched ballistic missile
China
China has the Dongfeng or 'East Wind' series of ICBMs which are also known as 'DF missiles'. These are a family of short, medium, intermediate-range and intercontinental ballistic missiles. DF 5A is China's longest range ICBM and is capable of striking targets within the range of 13,000 kilometers. The DF series are are land-based ICBMs.
List of ICBMs include:
DF-3 (CSS-3): Road mobile, 4,000-5,000 km
DF-4 (CSS-3): 1975, silo-based, 5,500-7,000 km
DF-5, DF-5A, and DF-5B (CSS-4): silo based, (1981) 13,000- (1983) 15,000 km, MIRV - 3 to 8
DF-31 (CSS-9): 2006, road mobile, 7,250-8,000 km range.
DF-31A: 2007, road-mobile, 11,270 km, MIRV - 3
DF-31B: 2015, road-mobile, unknown range and MIRV capability
DF-41 (CSS-X-10): 2010, road-mobile, 12,000-15,000 km MIRV - up to 10
Israel
Jericho III is a road mobile ICBM which entered service in 2008. It is a three-stage solid propellant missile with a payload of 1,000 to 1,300 kg with a range of 4,800 to 11,500 km. An upgraded version of the Jericho III was successfully test fired in November, 2011 by Israel.
France
The M51 SLBM is a submarine-launched ballistic missile deployed with the French Navy. It was inducted into service first in 2010. It has an operational range of about 8,000-10,000 km. France only deploys submarine-launched ICBMs, with all land based IRBMs decommissioned.
Pakistan
Despite its tall claims, the longest range missile in Pakistan happens to be Shaheen-III ballistic missile. It has an operational range of 2,750 km which was test fired for the first time by military service on March 9, 2015.
