WASHINGTON: The Biden administration is close to approving the shipment of longer-range missiles packed with cluster bombs to Ukraine, giving Kyiv the ability to cause significant damage deeper within Russian-occupied territory, according to four US officials.
After seeing the success of cluster munitions delivered in 155mm artillery rounds in recent months, the US is considering shipping either or both Army Tactical Missile Systems (ATACMS) that can fly up to 306km, or Guided Multiple Launch Rocket System (GMLRS) missiles with a 72km range packed with cluster bombs, three US officials said.
If approved, either option would be available for rapid shipment to Kyiv.
Ukraine is currently equipped with 155mm artillery with a maximum range of 29km carrying up to 48 bomblets. The ATACMS under consideration would propel around 300 or more bomblets. The GMLRS rocket system, a version of which Ukraine has had in its arsenal for months, would be able to disperse up to 404 cluster munitions.
With Ukraine's push against Russian forces showing signs of progress, the administration is keen to boost the Ukrainian military at a vital moment, two of the sources said.
The White House declined to comment on the Reuters report.
The decision to send ATACMS or GMLRS, or both, is not final and could still fall through, the four sources said. The Biden administration has for months struggled with a decision on ATACMS, fearing their shipment would be perceived as an overly aggressive move against Russia.
ATACMS are designed for "deep attack of enemy second-echelon forces", a US Army website says, and could be used to attack command and control centres, air defences and logistics sites well behind the front line.
Kyiv has repeatedly asked the Biden administration for ATACMS to help attack and disrupt supply lines, air bases, and rail networks in Russian occupied territory.
Last week Ukraine's Foreign Minister Dmytro Kuleba said he and Secretary of State Antony Blinken had discussed the US providing the long-range missiles and he hoped for a positive decision.
"Now is the time," one of the US officials said as Ukraine's forces are attempting to pierce Russian lines just south of the city of Orikhiv in an attempt to divide Russian forces and put its main supply lines under threat. ATACMS or GMLRS with this capability would not only boost Ukrainian morale but deliver a needed tactical punch to the fight, the official said.
The US plan is to include the grenade-packed weapons in an upcoming draw from US stockpiles of munitions, according to the four US officials, who spoke on condition of anonymity because of the sensitive nature of the plan.
At present Ukraine has only one US-furnished cluster munitions, the 155mm rounds that were announced in July.
The new weapons would augment Ukraine's current 72km range GMLRS rounds, a version that blasts out more than 100,000 sharp tungsten fragments, but not bomblets.
Made by Lockheed Martin, ATACMS come in several versions some of which can fly four times GMLRS' range, and their use could reset battlefield calculus.
The Presidential Drawdown Authority (PDA), which allows the administration to take from US stocks and ship to Ukraine has proven to be the fastest way - days or weeks - to get armaments to Ukraine.
In the interim period - ahead of the ATACMS arrival - necessary software upgrades could be performed on launchers including the M270 and High Mobility Artillery Rocket Systems (HIMARS) which Kyiv has been using on the battlefield, two of the officials said.
But because no final decision had been made, it was unclear if the weapons would be included in the next PDA. The weapons could come in a PDA as soon as this week, around a Sep 19 meeting of the Ukraine Defense Contact Group at the Ramstein Air Base in Germany.
President Joe Biden may ultimately decide against, or delay a decision on the transfer.
Cluster munitions are prohibited by more than 100 countries. Russia, Ukraine and the United States have not signed onto the Convention on Cluster Munitions, which bans production, stockpiling, use and transfer of the weapons.
They typically release large numbers of smaller bomblets that can kill indiscriminately over a wide area. Those that fail to explode pose a danger for decades after a conflict ends.
Washington has committed more than US$40 billion in military assistance to Kyiv since Russia launched its full-scale invasion of its neighbour on Feb 24, 2022.
