A great article from Janes and unusually, free to access.
The article says some of the 60mm systems will be retained for RM/Para use but most will go into extended storage, which I suppose is better than being disposed completely.
Jed wrote a great article about future choices on mortars, well worth a read[browser-shot width=”600″ url=”https://www.thinkdefence.co.uk/2012/01/mortars/”]
Compare the old 2″/51mm
To the Hirtenberger 60mm
To the L16A2 81mm
As a very quick thought, given the size/weight of the Hirtenberger 60mm mortar, logistics issues, difference in lethality, availability of 40mm and other systems, and cost pressures, I can see the logic in concentrating investment on the incredibly effective 81mm.
