What are these missiles with cluster bombs the US can supply to Ukraine?

Defense Express writes about it. 

The Biden administration is nearing a decision on transferring missiles with cluster munitions to Ukraine. After Ukraine's successful use of cluster 155-mm DPICM projectiles, the White House is considering providing Ukraine with either GMLRS or ATACMS cluster-equipped missiles. However, President Biden is cautious about escalating tensions and has not rushed the decision, as reported by Reuters.

Specifically, the term "GMLRS-type" likely refers to M26 unguided rockets with a limited range of 45 km. These rockets have a cluster warhead and are considered more powerful than DPICM cluster 155 mm projectiles.

Regarding ATACMS missiles with cluster equipment, there might be two options:

• ATACMS Block I (M39, MGM-140, or MGM-140A) with a range of 165 km, a cluster warhead weighing 570 kg, and 950 M74 submunitions. Each submunition can cover up to 15 square meters, with a probable deviation from the target of up to 250 meters. The guidance system is inertial, using a laser gyroscope.
• ATACMS Block IA (M39A1) with an extended range of 290 km, a reduced warhead weight of 150 kg, and 300 M74 submunitions. It utilizes a combined guidance system.

The decision to transfer these missiles to Ukraine could have significant implications in the ongoing war.
