Re: F-35B Lightning (RAF & RN)

The delay of the F-35 able to complete IOT&E due to delays of 'F-35 In-A-Box' (FIAB) proving it can operate in a high threat environment against peer enemies pushing back Milestone C, full production authority to possible 2021, but seems to have little effect as high production rate continues un...

Re. the purported missile attacks October 2016 on USN ships by the Yemeni Houthi in the Bab-el-Mandeb strait and the Burke destroyer Mason shooting down Chinese anti-ship missiles. Why 'purported'.

Re: Type 31 General Purpose Frigate [News Only]

If understanding correctly MIRADOR only operational in daytime and fair weather as no radar, laser would not operate at night, in heavy rain, fog, snow, smoke etc to give necessary range info with the passive IR camera, whereas the STIR with its radar makes it a 24 hour all weather system. Though B...

Re: Type 31 General Purpose Frigate [News Only]

Jane's T31 article posted above by Aethulwulf lists options for gun fire control, surprised no mention of the Bofors option of an on-mount TV camera and muzzle velocity radar with digital fire control system for the 57mm and 40mm guns, presume due to Babcock/Thales systems agreement. "Alternati...

Re: Royal Navy Gunnery Discussion

Definitely worth noting that even the Italians, who prop up gunnery based anti-air more than any other nation, still saw fit to have high end radar and Aster-30 capable silos on their PPAs. PPA also has following guns fitted - 1 x OTO Melara 127/64 mm with Vulcano extended range ammunition and AAHS...

Ponoglo earlier queried the effective range of a 57mm 3P round in AAW mode, googled unsuccessfully but found Leonardo PR of 2014 trials with their 76mm SR and saboted DART sub-calibre projectile, more than 5 km (say 5.25 km?) against targets at low and very low altitude.

Re: Royal Navy Gunnery Discussion

A lot is going to depend on the sensors we are able to fit on the T-31 to control both the 57mm and 40mm. Can we afford a level of sophistication that allows these weapons to achieve their advertised potential? The Bofors 40 and 57mm come optionally fitted with an on-mount TV camera and muzzle velo...

Re: Royal Navy Gunnery Discussion

But we will have 2 x Bofors 40 MK 4 on Arrowhead whereas IvH has one Millennium 35. 2 x 9.75 kg = 19.5 kg, plus the advantage of having two guns rather than one is that they can engage two different target simultaneously and at approx twice the range of the 30mm DS30M we currently mount on the T23....

Re: Current & Future Escorts - General Discussion

The ultimate Phalanx replacement will be a laser based system. I have no problem with this but until then Phalanx will keep going There is no reason to chose the 40mm over the 57mm which is superior in every way - put it on the Rivers and future MH(P)Cs - but the T45s and T31s should be 127mm.

Looking at the new Finnish Pohjanmaa four class 'corvettes' in build ~Euro 1.3B/£1.15B/4 = ~£288M each (triggered by contract award to Saab Thursday). Compared to T31 Pohjanmaa budget approx 15% higher if comparing apples apples figures and with no detailed breakdown could be questionable, A shorter...

Re: Royal Navy Gunnery Discussion

Quick look at the 40mm CTA, design imperative was for a compact short round, 65 x 255mm, to fit more shells into the very limited space of turret of army vehicles eg Ajax/Warrior. ThinkDefense "Anecdotally, the cost of the new ammunition is said to be ‘eye watering'" The Nexter/Thales Rapi...

Re: Royal Navy Gunnery Discussion

40mm stopping power out to 9 km In the trials (as for LMM) extending out to 6 km was mentioned - so the reach is also different (both much better than the 30 mm, obviously) Think 40mm 9 km range would be optimistic, my understanding the effective range of the Bofors 40 in the AA role will be ~ one ...

The 76mm gun in the old USN FFG 7s did not have a good reputation for reliability and the US DoD DOT&E reports on accuracy of the 57 on the LCS left a lot to be desired, it was only in last couple of years it shown improvement. The 76 shell is marginal for NGFS as low in weight and short range 1...
