My sincere apologies for my lack of participation on this means 😞
In my long overdue response to this topic, after time to deliberate, Rickshaw and apophenia I'm liking your notion of the MECAR 90/28 mm gun 😯, especially seeing that in my Alternative ADF ORBAT, I have the Australian Army using Canon Antitank d’Infanterie 90 mm (CATI 90) from 1954 to ~1962. In which case I could have the realistic case of the MECAR 90/28 mm guns being removed from the chassis and put into 'War Stocks', and then in 196?, with the operational need of the DHC-4T Caribou gunships, some of these MECAR 90/28 mm guns could be utilised 😯
Now from what I've been able to find, "the total weight of the MECAR 90/28 mm gun is 274 kg and featured a hydraulic recoil system. The gun had a recoil of 2500 kg and a recoil length of 40 cm, both of which are relatively low. The breech mechanism was semi-automatically cam-operated, the cases were ejected automatically."
So with the forums knowledge, do we think this MECAR 90/28 mm gun would be viable in the DHC-4T Caribou gunship? Maybe a low recoil cradle modelled on that of 105mm howitzer employed on the AC-130 could be utilised, to save cost and time......
(Please note, I also envisage the Australian Army employing the 90mm in the fire-support role, as opposed to the 76mm L23A1in my Alternative ADF ORBAT, so ammunition comparability will be there - especially as I picture these DHC-4T/DHC-5 gunships being versed in forward operation with Army units as part of their SOP's....)
Please note, someone from another forum sent me this:
"The 90mm/46 KEnerga, sometimes marketed as the Cockerill Mk8, was offered as a towed gun in the late 80s/early 90s. KEnerga a confusing program, I believe initially developed by MECAR but later marketed in a collaboration with Cockerill. MECAR had previously sold a towed version of its 90mm/28 light gun as well."
So I'm wondering if the RAAF would be able to incorporate this '90mm/46 KEnerga' or the 'towed version of its 90mm/28 light gun' for the larger, more powerful DHC-5 Buffalo gunship.
(Would love to know more about this '90mm/46 KEnerga' or the 'towed version of the 90mm/28 light gun', if anyone, with the exception of GTX who has already sent me what he's got 😯)
