In 2013 Janes reported that the Hirtenberger 60mm mortar purchased under an Urgent Operational Requirement would only be retained for RM/PARA use and the rest would be withdrawn. (read the Hirtenberger datasheet here)

A picture last week from the MoD shows one in action during a training exercise

They look quite large, and heavy.

Compare to the old 51mm (2″) mortar.

The French/German Fly-K system (Lance Grenade Individuel in French service) always looked a more natural replacement, now we are best friends with the French perhaps they will let us try some of their Fly-K’s as well as artillery and armoured vehicles?

Did we include the Fly-K in evaluation for the 60mm?

Would be interesting to see the trade off’s and a comparison between the 40mm UGL, Fly-K, the 60mm and even (whisper it) rifle grenades!

60mm is a standard calibre and in widespread use so there are plenty of natures available, the Fly-K on the other hand is only in use with France and the UAE. The protection module looks interesting and the visual and acoustic signature is very low.

Anyway, a few bits of media…
