Apparently not for the purposes of being USED as cluster munitions.
Interestingly, the following backs what GrauGeist suggested:
"Ukraine has broadened a request for controversial cluster bombs from the United States to include a weapon that it wants to cannibalize to drop the anti-armor bomblets it contains on Russian forces from drones, according to two U.S. lawmakers.
Kyiv has urged members of Congress to press the White House to approve sending the weapons but it is by no means certain that the Biden administration will sign off on that. Cluster munitions, banned by more than 120 countries, normally release large numbers of smaller bomblets that can kill indiscriminately over a wide area, threatening civilians.
Ukraine is seeking the MK-20, an air-delivered cluster bomb, to release its individual explosives from drones, said U.S. Representatives Jason Crow and Adam Smith, who both serve on the House of Representatives Armed Services Committee. That is in addition to 155 mm artillery cluster shells that Ukraine already has requested, they said.
They said Ukrainian officials urged U.S. lawmakers at last month's Munich Security Conference to press for White House approval.
Ukraine hopes cluster munitions will give it an edge in the grinding fight against Russian forces in eastern Ukraine.
The Ukrainian government has said publicly that it wants U.S. cluster munitions. The petition for MK-20s - also known as CBU-100s - has not been reported previously.
The Ukrainian Embassy referred Reuters to the defense ministry in Kyiv, which did not immediately respond to a request for comment."
The above is from a journalistically credible source too -
Exclusive: Ukraine seeks US cluster bombs to adapt for drone use - lawmakers
Personally, I smell obfuscation. Any significant delivery of MK20s equates to a hell of a lot of drone-drops. And that order AND the request for 155mm cluster munition shells being blended together looks a little like the creation of a potentially deliberate fig-leaf to me.
As an old South African mate used to say 'Time to $hi£ of get off the pot, bru'. Is the US going to supply 'full on' cluster munitions. Or bomblets. And if its the latter, why not extract the bomblets first from the MK20? Surely they have to be relatively easy to remove for checks, maintenance and servicing anyway?
A cluster bomb is a relatively simple 'dumb' munition. Sending it as the complete item, if the actual intention is to use the bomblets, looks disingenuous to me. Its also something of a distraction to the question of the 155mm shells, which presumably use a different submunition anyway.
Theres the waft of kippers surrounding this whole story...
