As part of the US defensive aid, Mk 19 40 mm automatic grenade launchers were delivered to Ukraine.

This is reported by Ukrainian Military Pages with reference to information discovered by the user @thelema _ boy _ from Twitter.

@thelema_boy_ paid attention to the NSN 1010-01-490-9697 identification code, which can be viewed on one of the “black pallets” delivered to Ukraine on January 28.

According to the NATO Multilingual Supply Classification Handbook (ACodP-2), the NSN code 1010-01-490-9697 match to such a supply item as “Machine Gun, 40mm, MK19 Mod III.”

The classifier has already been introduced in the Ministry of Defense of Ukraine under the name “Unified classifier of supplies.”

According to the number of “black pallets” in the photo taken during the loading of the aircraft, which were made public by the US servicemen, it can be concluded that only on January 28 several hundred Mark 19 grenade launchers were delivered to Ukraine.

Today, the seventh American plane delivered 85 tons of 40-mm ammunition for grenade launchers to Ukraine.

It is also possible that the Mk 19 grenade launchers were already supplied to the Armed Forces of Ukraine as part of other shipments, because 40-mm ammunition s have repeatedly been part of the cargo of American aircraft, including in the fall of 2021. As an example, we give a photo of unloading boxes with 40-mm ammunitions from an American aircraft at the Boryspil airport on October 10, 2021.

According to the marking, in the boxes in the photo, 40×53 mm high velocity grenades M430A1 HEDP with a universal debris-armored grenade (capable of punching 76 mm steel). Each such standard box contains 32 ammunitions connected by links M16A2 into the tape.

The Mk 19 40 mm automatic grenade launcher (Mark 19) entered U.S. military service in the late 1960s, first seeing action during the Vietnam War and remaining in service to the present day.

Unlike available in service in the Armed Forces of Ukraine AGS-17 Plamya, has a wider range of ammunition:

• the M430 HEDP 40mm grenade will pierce armor up to two inches thick, and will produce fragments to kill personnel within five meters and wound personnel within 15 meters of the point of impact.
• the fragmentary M383 and M384
• the educational M385

The modification passed to Ukraine was produced between 1981 and 2000 in the United States. Also produced under license in countries such as the Republic of Korea and Turkey.
