the 120mm mortar is capable of firing guided munitions, if its taken out on a vehicle patrol either inside a vehicle or towed, it can do a decent job against the kind of threats the DF operates. its not fantastic, it has issues, but it has the capability to provide the organic fire support the DF needs in the kind of PK/PE operations the DF is likely to be undertaking in the near to medium term.
you could utilise it in two different ways: firstly with the patrol. when things go bad the vehicle carrying/towing the mortar puts his toes down and gets out of the immediate danger area. unload/unpack the mortar, synch with the ISR/ISTAR to get targetting, and let the rounds go asap. secondly you could operate it as a mobile firebase - it follows the patrol while keeping the patrol within its fire bubble, goes firm as often as possible and when the patrol goes into an area of heightened threat like a mountain pass, areas of cover, bridges etc.. laser guidance is the easiest to do, you just give the patrols a GLD (which aren't cheap...), and if you buy a a very good GLD you could use GPS guided munitions.
its not as good as having an AH sat over the top of you, but its in the inventory (save the PGM's..), and given the cost of having an AH sat over the top of you its actually achievable.

The question of local production is interesting, the total production of the Terrex is 135 unit. Would suggest that a 300 unit order would justify a production line in Meath.
I have long like the Terrex but the it has not made the cuts for the Land400 Phase 2 competion. Of the remaining I would go for the AMV.
It is already in service with our Swedish and Finnish battlegroup/UN buddies and armed with the turret of the CV9035 it cuts a fine figure. Can also mount the twin 120mm AMOS mortor turret.
.
Let order the AMV35 to replacement the Piranha APC
- AMV with an OTO Melara HITFACT120 turret as replacement for the AML90's
- AMV with either AMOS or NEMO 120mm mortor as replacement for the AML60's
- AMV with a DENEL T7 turret for long range fire support
+ Command, Ambulance, Recovery, Engineering and ISTAR/RSTA versions.

If you established a production line in Ireland, given the sad (industrial-related) history of any motorised vehicle in Ireland, since time began, you'd be on a hiding to nothing. Virtually all such ventures have failed thru industrial action, pricing themselves out of the market or Govt interference. The only aspect of that kind of thing that has succeeded is firms like Combilift or people assembling kits of vehicles and even they have failed. Limited production of specialist vehicles like ambulances and fire engines has failed in Ireland before and to use an aviation comparison, successful companies like Airmotive and a host of overhaul firms like TEAM, FLS, SRT 9all of which were making money but closed by their hosts for political reasons) and so on have gone to the wall. I'd rather hand the plans to Hyundai and let them churn them out....also, I wouldn't let the DF have any involvement in any kind of production or maintenance facility. They can't deal with what they have...

It is interesting to see that we now have an Irish company called Innalabs producing MEMS type gyros of the type that I referred to in those posts you quoted from 2013.
For the non-techies, these devices can determine north by sensing the rotation of the earth rather than by sensing the earth's magnetic field.
This makes them insensitive to local magnetic variations and suitable for smart aiming systems that can be attached to steel items such as artillery/mortars.
Gyro-based north finders are not new but they traditionally used physical spinning masses or fibre optics. The MEMS ones are ideal for lightweight and low power applications.
Innalabs can currently achieve 3/4 Mil accuracy in 90 secs and 1 Mil if you have more time to average readings.
It would not be beyond the bounds of possibility for the Defence Enterprise Committee to organise a project with the DF, Innolabs and a suitable 3rd level research centre to develop a smart integrated aiming solution tailored to Irish needs.
InnaLabs® is Europe's No.1 inertial sensor provider for Space Micro-launchers, Satellite Constellations, and Telecommunication Satellites.

Archimedes,
It's a nice idea for the 'what if...' pile, but do you really think that if you spent €1m on such a project you'd get more than one single PGM prototype out of it?
If you went to the US and bought under FMS you'd get about 50 GPS, Laser or IR guided 120mm rounds delivered within two weeks.
I also see no export market - why by from an obscure Irish company with no history, and subject to the political whims of the Irish government when you can get something tried and tested from a government that tends to take the long view when it comes to defence sales?

It isn't necessarily about export potential (although hopefully it would be a byproduct). It is about Irish industry getting access to DF expertise and visa-versa in order to solve a problem at low cost. There is a sub chapter in the WP on it.
I don't know to much about the black art of arty apart from sitting in the simulator and watching a battery fire but a proper system to greatly improved accuracy would be a much cheaper alternative to PGMs.Last edited by DeV; 25 August 2016, 21:10.

A PGM Artillery or mortar round will hit the right apartment in a block of flats at maximum range with just one shot - even under perfect conditions with radar correction a 105mm firing unguided munitions you'd fire a dozen rounds before you got within 100m of the block of flats, let alone the right apartment. To get the right apartment you'd have to turn the whole thing to rubble.
Hardly reducing collateral damage to the minimum....

Firstly, guided munitions are a whole different ball game and not what was suggested here.
A gyro based aiming system would not improve the accuracy of our weapons one iota over what you would get if you spent a half hour laying them out in traditional fashion.
It would never give you the accuracy of guided munitions but that does not mean that it is not worthwhile.
The ability to drop a 105/120 off of the back of a truck/ltav and be ready to fire as soon as it is in action is highly desirable.
Being networked to the CP also speeds things up, eliminates mistakes and provides inherent checking of the lay.
Sure, others are already doing this eg the UK LINAPS but technology such as what Innalabs have can make the whole thing much smaller and lower power.
Why buy an aiming system from an obscure Irish company? Well if it had successful trials with the Irish DF, was compact enough to clamp onto a 120mm barrel and could do 24hr continuous use with one lithium sincgars battery, you might be surprised.
ps: why limit the ambition to a 120. If you make it light enough and small enough that the whole self contained unit will clamp to an 81mm barrel, then every Bn commander in the world will want them.
pps: here is an existing "dismounted" system based on fibre optic gyro (FOG) technology. It must be wired to a separate power supply containing 8 Sincgars batteries and has a battery life of 13 hours http://ausar-web01.inetu.net/publica...ts/SA_0710.pdfLast edited by Archimedes; 26 August 2016, 01:09.Si Vis Pacem, Para Bellum

It is about innovation.
This would actually be more about an Irish company developing a solution to a worldwide problem than the DF buying a system. The company gets access to DF equipment and expertise, the DF gets access to new equipment (for trials) and expertise and maybe a 3rd level institution comes in too. The DF doesn't necessarily have to buy it (that is the beauty) or any system.
Archimedes,
