river class opv upgrade

I suspect the minimum they’ll receive is Martlet on the 30mm. A good example is the Scheibel Camcopter 100 which has an operating range of up to 180km from its control station and is capable of mission durations up to 6 hours. How about keeping them under the white ensign and reforming the Home Fleet? They may still have to do that but the B1’s should be retained to do this (paid for out of Dept of Ah & Fisheries budget !) Every European state has a much greater presence in their own waters. Wouldn’t the 5in gun and the Mk41 be more relevant on the T31? Firstly good seakeeping for all-year ops from SWAPPS to Shetlands and beyond. So it is all about Commercial Off The Shelf for fire control, Bofors 40mm main gun (but with below deck reloading because the 100 rounds a MK4 carries, without deck penetration, is gone within 20 seconds at a full rate of fire); a 30mm on each waist with five coaxially mounted LMMs (to augment the 40mm for surface and slow air targets). As the Type 31 won’t be using them, I think there should be some (three?) There seems to be lots of headquaters costing money and manpower, there is no true cost to the treasury as the budget is spread over several forces, the RN could use the savings for investment into the fleet of war and people retiring from the RN could go into the new Coast Gaurd force if they want to. The last of five River Class Offshore Patrol Vessels (OPVs) designed and built for the Royal Navy by BAE Systems has been named at an official ceremony. 57mm already purchased for T31 on to the front. USV etc). Switch departments! Compare Wildcat, MTOW 6000 kg, rotor diameter 12.8m with the smaller AS565 Panther, MTOW 4500 kg, rotor diameter 11.94m. The River class is a class of offshore patrol vessels built primarily for the Royal Navy of the United Kingdom. Do they have any miles left in them? Include modular facilities for the Royal Corps of PR Specialists and Photographers and he’ll be fine. So now we have a OPV plus with Corvette electronic suite at no extra cost for the kit extened survalance range upto Sea State four and 15 degree roll. This project is code for ‘ we are going to lose 3 Type 23s and the Type 31s won’t be ready so we need to deploy the Batch 2 Rivers.’ As I see things, in order of ££ 1.LMM will enhance against FIAC and against helicopters but has no true AA or anti ship missile capability 2. ( Log Out /  40mm main gun, a pair of 30mm with Lmm on the waist and a fire control system backed by containerised rotary UAVs. Crucially, this combination is practical and affordable. hey-ho. The F35s identify target and the Merlin’s operatining under the fleet air protection zone launch the munitions and guided by the F35s. However a UAV could fit nicely and be of great utility. It could make these ships much more lethal inside 5,000 yards. What we need for item-5 is to, – bolt on a CIWS base-mount on this ring – wire the power, data-link cable wired to CIC, and pipes for cooling water – reserve a space for a console in CIC Then if you bolt on the CIWS on this mount, and bolt on the console in the CIC, its done. In some ways perhaps the most successful acquisition of the last few decades. Accommodation for boarding parties. There. So, if RN “needs” a hull to fill these gap, it is around 2023-2026 (may be -27, as T26 and T31 will be in service very late this year). A Bofors 40mm adds some AA and anti missile capability 4. A&P Defence has secured a programme of maintenance work and repair packages to old and new River Class Offshore Patrol Vessels (OPV) in Falmouth, as part of an ongoing support contract with BAE Systems. However, the ship with the 57mm Bofors, using guided rounds combined with the NS100 radar would make quite a formidable anti-aircraft/missile combination. So, before we compare what’s been done to Brazilian or Thai ships, we need to understand that they are almost certainly operated under very different stability standards to the RN. Its easy to understand why upgrades might be in order when you consider some of the duties that these ships might be called upon to perform. Therefore, you still need to put a lot of lead downrange to effect a hit. A Bofors 57mm adds range and offensive hitting power 5.NSM and / or helo expensive and out of place, send a frigate. Whether you ride dirt bikes, all-terrain vehicles, or a 4x4 truck, an off-highway vehicle is a great way to spend time together outdoors with your family and friends. Perhaps the most important addition however would be some form of beyond the horizon surveillance vehicle. If all you have is 30mm, then LMM is useful (or on a helicopter). We’re building T31’s specifically to operate in places like The Gulf and South China Sea. But it explains why you said they can’t man the new ones. A&P Defence and BAE Systems have recently agreed a two-year extension to a framework agreement which will now conclude in 2021. The latter cover (among other things) stability, structural strength, fire protection, escape and evacuation, manoeuvring and control and so forth. Adding a UAV good for anti piracy 3. Big and well armed enough to defend themselves and shipping in the vicinity and to have decent survivability/endurance, but also simple and cheap enough (hopefully) to be procured in greater numbers and allow the high-end surface vessels to concentrate on their primary role of escorting the fleet’s capital ships. The Baden-Württemberg-class frigates have water cannons, which is a good non-lethal way to deal with pirates. The site is run on a voluntary basis. I expect it’ll be used to escort commercial vessels in places like the Persian Gulf. This modern weapon weighs just 2.3-tonnes and is non-deck penetrating. In the future, drone FIACs will increasingly be a threat, so the more ammo a ship has the better. The problem is it doesn’t have the punch or flexibility of the larger 57mm (6 pounder!!!) We are better off making sure that all the Type 45s are in good nick by 2023, having the highest availability (including a Harpoon replacement). Counting “in RN hand” frigate number, the gap is in 2023-2025 for up to 2 hulls. They’d be perfect for home waters and Falklands defence. Purchase Starstreak II in 6-round naval launchers for a 7km/16k foot air-defence capability. The only thing Rivers could realistically be uparmed for is to deal with fast attack craft in areas where there are no subs and no anti-ship missiles. Granted the crewing and maintenance of the lynx will not be free but it’s reversible, temporary cost, as is the hangar if you do it right. However, the extended anti-missile range it would give would always be welcome. The whole design is very conservative. The image in the link above shows no SSTD and says “Merlin-capable hangar”, but doesn’t say if a Merlin will permanently embarked. Meanwhile, the Batch 2 River Class HMS Forth and her crew are in the final stages to resume trials and training. You might as well specify the even larger MQ-8C, which at least is a later model. Plus the Type 31s proposed anti-air capability isn’t great (just 12 CAMMs) and the Bofors 40mm is out of ammo in just 20 seconds. Don’t see the point in 1 if you have 3 (or 4). I’d call it a Sloop. please can was name them the Shannon and the Chesapeake? This is probably the best recommendation of the whole thread. My question is, what then, given your knowledge of the RN, is the basic outline design for an OPV for UK waters? Upgrades to survivability include fire safety and fire-fighting enhancements, watertight integrity improvements, better emergency lighting and full ballistic protection of the magazine. This not to suggest a reduction in T26. At least an ASW Merlin Mk2 operating from a frigate, carrier or land base can theoretically land on the OPV’s flight deck where they might be refuelled or re-armed. What is most obviously lacking from the Thai vessels and the upgrade options for the RN’s OPVs is real anti-submarine capability. Our allies must despair of a navy that was once the gold standard for navies throughout the world. So OPV plus to fight non state actors, do wide area surveillance and contribute to protection of merchant shipping. Its completely unrealistic to have another type in service and the Wildcat comes in 2 versions the HMA for the full anti sub work and the AH version for RM work, mostly on land but can be carried on deck. I don’t understand why the Royal Navy is messing about with Puma, a 7kg fixed wing with limited sensors and a flight ceiling of a few hundred feet. Missiles have a EOL on more than technology. The 40mm / 30mm mix would be perfectly adequate for policing operations and inner defence. “The new River Class offshore patrol vessels replace five Island Class offshore patrol vessels which entered service in 1979.” In February 2005, the UK Ministry of Defence placed a contract with Vosper for HMS Clyde, a River Class Batch 2 variant, to act as the Falkland Islands Patrol Vessel. More so given it can deploy Royal Marines, where having such capability is complimentary. With a very simple aviation support ship like the RFA Engadine or even one of those ships that gets everybody really excited on sites like this, an Absalon to act as a flotilla leader. T31 may be in the water sometime in 2023, but it won’t commission until some time in 2025 if we are lucky (more likely 2026 – later if not in the water on time). Thanks. Last time I looked the Arabian or Persian Gulf was a bit of cul-de-sac. Babcock has directly stated that A140 has the option of rafting the diesels if chosen at build which would further enhance its ASW ability. But one of the design drivers for the Castles was a flight deck because the helicopter in today’s marine environment the helicopter is important. The 40mm because it means you can comfortably out range any Kornet ATGM that may have fallen into the hands of Somali Rebels / Pirates and dominate the engagement, also gives a measure of AA. Perhaps use it to aim a SAAB anti submarine grenade system? Because its likely operating inshore or out to 200 mile EEZ, some mine warfare drone or multipurpose equivalent might be a useful addition should circumstances require. The Starstreak HVM accelerates to Mach 4+ in just over a second after leaving its tube. That said, using a purely diesel-powered vessel for sub-hunting, even if the engines were rafted, would be far from ideal. That is exactly my thought when I read RN Commander Operations comments. The complete Artisan system i.e. While you could in theory program a cruise missile to turn around & fly back, I doubt it would be recommended in case it got confused as to intended target. I have one slight concern about talk of armed UAVs and that is regarding payload. Yes. But they are equipped more like a 210. Our potential foes must be very content. I’m torn on giving it CAMM. Assuming that there is money for both, I would probably still spend the cash on something else like personnel and retention, a fleetwide UAV replacement for Scan Eagle, a platform agnostic containerised ASM, or the helicopter fleet (to name a few of what I see to be greater priorities). IH is capable of & has facilities for operating a towed sonar if required. Again the reality is if for example Iran fired of a land based anti Ship missile at anything both the UK & USA are going to be sending some pretty large amounts of Steel to the region. I don’t think we need to upgrade all 5, maybe 3. That’s pretty much it. Re: River Class (OPV) (RN) Post by Caribbean » Sun Sep 27, 2020 10:57 am If the money is there, I agree, but I suspect that any upgrade to the B2s will be financed out of the rounding errors on other projects. Best upgrade a river could get is a platoon of royal marines. I can’t imagine that swapping sensor packages (between optical/laser and radar) when on board is a good or practical idea so either something with slightly more payload capacity but still able to be housed and maintained in a standard 20′ container is needed (my preference since I think an “S-100 Max” would have huge export potential and be a good thing for UK industry to develop) or some decisions have to be made between optical sensors (including laser designator), radar surveillance capabilities such as Thales I-Master, and weapons. In this case, we get the remaining 1B GBP. A total of nine were built for the Royal Navy (RN), four Batch 1 and five Batch 2. I suspect that meeting those requirements was not without it’s challenges, which means that provision for Capability Updates or through life growth may (I say again, may) be limited. The Government has always invested a lot of effort into the Gulf. The fact that you probably can’t hit them at that range doesn’t matter (it was a warning shot wasn’t it). The OPVs are there to do the low intensity missions so that actual warships are freed up to deploy to places like the Gulf. For an offshore patrol vessel, this would really enhance the ship’s situational awareness, especially what’s happening just over the horizon. So, with 19 escorts, 6.33 will be able to be deployed, if proper operating cost and man-power are provided. Have the contracts been signed? Surely it is too valuable to use for NGS. “Enhancing the lethality of the Batch II Rivers” sounds like someone has been reading the Thales brochure on LMM. My one suggestion would be an 8-cell Spike NLOS Naval launcher that, with the UAVs, would give offensive punch to 30 kilometres. If it’s causing the RN issues then perhaps a leaf should be taken out of the American book and the OPV’s transferred to a beefed up HM’s Coastguard (which in turn can come under RN control in a serious conflict or at least RN control within the AO of a lower intensity conflict), an RFA but with guns so to speak. What an excellent idea. The again if a OPV Plus Plus gets into a major missile war then something has gone really wrong and you need to call the big ships in. If B2 is to help fill the gap, they have 3 years to get it competitive. It’s not as mature as the smaller Camcopter or the V-200 Skeldar, but it might be the closest to your “S-100 Max” that’s near deployable. I think we have passed that point. How would an OPV designed to RN requirements differ? It’s not well armed enough for anything else. So the goal is “15 manned”. Brace for impact. I’d also fit MASS decoys to provide another layer of defence against anti-ship missiles as well as 2 DS30Ms enhanced with LMMs to provide another layer of defence against FIACs. Save the Royal Navy looks at how they might be upgraded. Yes I know it adds requirements for fire fighting etc. I can’t see any need to base a helicopter on one. Forth and Medway are already on their way. Its average sea-going days was 120-140 days around 2010, but now it is 70-90 days a year. Then you need a hangar, spares and maintainers. The reason for this is the missile is classed as a within visual range weapon, so can be used with the current rules of engagement. To catch drug or arms runners, the Rivers are too slow. Cost of my suggested upgrades should be minimal. I’m just half of the opinion now that, since we’ve got them, if we up arm to corvette, then maybe, just maybe, they place hold for a batch 2 T31. The 30mm guns could be fitted too but this space could be used for mini guns and Sea Ceptor. Having a helicopter aboard at all times, particularly an armed aircraft, could help the ship with both peacetime and wartime missions. If it is the later it should not mean that the RN budget is cut. 2024 -T23: +185 2025 -T23+T26+T31: 185+185-157-100 = 113 2026 -T23+T31: 113+185-100= 198 2027 -T23+T26+T31: 198+185-157-100 =126 2028 -T23+T26-T31: 126+185-157-100 = 54 2029 -T23+T31: 54+185 -100 = 139. Enough to take out pirates, boat swarms, helicopters and UAVs, and give another Corvette a bloody nose. Option-2: Order TWO more T26 with 1.6B GBP or so, and re-role 300M GBP to “slightly improve” T26 armaments, and use remaining 100M GBP to make TWO of the five River B2 a “super OPV” = say, three 30mm gun all with LMM, and a 20 mm CIWS (in place of the crane), with UAVs. One thing I would change is go for 57mm instead of 40mm for main gun since this is something that can’t really be switched out based on role. The FIPV does need a flightdeck for operations with the deployed helo flight at MPA. The S100 would be best suited to our Border Force cutters, etc. ( Log Out /  Is heavy investment in upgrading her weaponry the best use of resources when her light armament is appropriate to her role as a patrol ship? Aside from fire control, it leaves everything else, flyco, firefighting, cranes etc in-situ. A&P Defence and BAE Systems have recently agreed a two-year extension to a framework agreement which will now conclude in 2021. Below are some outline suggestions for enhancing the OPVs. At least 3 batch 2 up gunned to the plus with 40mm, 3x 30mm and camcopters with martlets to extend range one in the caribean, one in the med/black sea and kept back for general duties, the other 2 batch 2s should get the 57mm, 2 x 30mm camcopter with martlets one being based in falklands the other in the north sea to keep russians at bay. If you are going to fit NS110 to B2, then really need to fit NS200 to T31. What happened to the Lynx helos? The sum I estimate for all-five is around £25-£30 million and maybe less. In this article, we consider some of the options and implications for upgrading these vessels. Adding a medium calibre gun and helicopter hangar would bring the river class more in line with many foreign OPV designs. Maybe. The Batch II have accomadation for 50 marines plus kit, they can at a push carry 90 but they need camp beds. So two S-100s and a base station. Replace the current gun with a 57mm. The obvious answer to up-arming the B2s and to keep costs down, is to keep the equipment required with what’s currently or will be in service. However, Unless the RN can get some AW159 from the army, I doubt any helicopters would be available, even if a (telescopic?) Telescopic hangars are a compromise solution that makes good use of limited space. Wikipedia quotes a single Spike NLOS as 70kg. With five new platforms possessing good endurance, seakeeping and basic survivability features, the RN has the opportunity to significantly improve its order of battle without enormous expenditure. 57mm maker sence along with 2x 30mm plus the camcopters fitted with martlet. Use of reservists or part-time civilians will solve the manning problems since essentially only 2 vessels need to be ready at anytime with the other 2 in reserve or repairs. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. If you haven’t shot down that AShM in less than 20 seconds from when it was in effective AAW range, then it has quite likely already hit you (or missed you as the case may be). Originally, the plan was to replace the Batch 1 River class  Offshore Patrol Vessels with the newer Batch 2 vessels. Enhancing the Royal Navy’s batch II OPVs | Save the Royal Navy 40mm shells are cheaper than LMM missiles & P3 ammo has additional uses that the LMM can’t match. https://www.telegraph.co.uk/politics/2020/02/05/britain-boosts-fishing-patrol-force-battle-brussels-looms-eu/. Taking a Schiebel S-100 as a benchmark, that is quoted as having a maximum payload of 50kg (https://schiebel.net/products/camcopter-s-100-system-2/) which I assume excludes fuel. So I reckon option 1+2 is the way to go for Somalia anti piracy and Iranian Revolutionary Guard FIAC. Much cheaper vessels could do this job. The helicopter is nearly as important at sea at the ship. Also fast enough to run away if it catches wind of something it can’t handle. Very different from 7 Island class Patrol vessel and 2 Caslte class OPVs in early 1990s. In the Asia-Pacific region where the mission may be to join a coalition to face down the might of the Chinese, a greater level of weaponry might be needed in order to be taken seriously both by allies and adversaries. Looks remarkably like a batch 1. An upgunned River isn’t the right platform. Ultimately the calculation is – if I attack this thing, do I end up taking a massive risk that the response is unpalatable. (bring the crane back in EEZ mode). ( Log Out /  eg RAN operate block 2 Harpoon, RN block 1. It uses a 220kg impact fused warhead – not something to mess with. Saying River B2 is not maximizing its use is not correct. The problem with operating the Rivers against pirates in places like Somalia is that AShM have been fired at naval ships from groups in countries relatively close by. I’d fit the Martlet option for higher threat environments (east of Suez). Will it have a Merlin HM2? At the same time, enhance Aviation facilities for helicopters and UAVs. The C2 flotilla would operate on a “single platform, double crew concept” – ships would be forward deployed but crews, as they do now in the MCMV fleet would rotate – all training completed in Plymouth through FOST. Thanks for that link. Sea Cepto can attack surface targets. Want to test fire 20 rounds of 40mm, not a problem. The four River class Offshore Patrol Vessels (OPV) operating with the Royal Navy are expected to reach the end of their service by the end of the decade. Add option 3 and you have ‘some’ defence against Yemeni rebel AShM but not against Iranian Navy who are professionals. When T26 and T31 commissions, (up to 3) up-armed River B2 can easily reshaped as a specialist (super-efficient) EEZ patrol vessel, as is now. However, we need to decide what we want or more likely need these Ships to do. If we did want coastal ASW, would a mini towed array sonar, like the DSIT Swordfish, that only needs a small winch & thin wire, be suitable? Despite their BAES heritage, the Thai vessels are equipped with the Thales TACTICOS combat management system integrated with Thales-made sensors and platform management system. I know harpoon is end of life but surely it would be useful to defend against swarm attacks or to blow pirate skiffs up. Rather radical, I actually hope to cancel T31 program, to save 2B GBP. Before we even think about fitting any type of towed array sonar on the B2s we need to fit on Type 31 Corvettes first. (not arguing – genuine question). Is this already in the UK inventory or will a completely new support chain have to be established to maintain it and supply it with spares and ammunition? Also, it must not be expensive, because it will eat the budget and even delay the T31/T26 build. May be overkill for some situations but gives more capability than 40mm, is appropriate for most east-of-Suez roles, and would take advantage of the fact that you have installed ARTISAN. To be out there, what about a Sinbad mount & Mistral missiles? If an Oerlikon Millennium Gun would fit on the front where the current Bushmaster is all the better. But uparmed Batch 2 Rivers could do that job at a fraction of the cost and they could do it now, now it 7 years time. The RN needs to hold to its policy of making sure it OPVs are clearly nothing more than cost effective constabulary vessels and should not be facing more Greater threat that a drug dealers fast boat, modern pirates or a hard day in the North Sea. It is because we potentially have a REAL task here. Trent, Tamar and Spey will receive the minimum enhancement to enable them to replace the T23s we will lose and be useful against drug runners and pirates in the Indian ocean; a containerised UAV and either LMM or a 40mm, but probably not both. You then have an OPV that is still an OPV but with bigger teeth. As, in place it will significantly lose the sea-going days and man-power friendly operation, you may need two of them to cover a place one was covering, and still you need 3 or 4 times more crew to do it, robbing these crew from other assets. If you go for that then you might as well just go for a Merlin and be done with it – though I think both are unsuitable due to a lack of permanent hanger. A Wildcat’s only of limited use for anti-sub warfare. Those latter requirements will be very different to the Trinidad and Tobago coastguard (original customer for River B2), Brazilian navy or Thai navy. Aviation helps in both law enforcement and military scenarios. Five-pannier LMM launcher mounted on the 30mm ASCG – trialled on board HMS Sutherland in July 2019. There is one additional option that could be installed on my verstion of the Batch IIs, if SeaRam was to be installed then rather than using Typhon MLS NLOS as you would only be able to carry either/or, have 2×6 launchers for Brimstone Sea Spear. The ASCG system according to Wikipedia cost the MOD US$30 million to purchase 26 for the Type 23 so I expect a new buy to be less than US$2 million per system and 10 would be needed for the OPVs or they can be taken off the retiring Type 23s. There arent any of course in production anymore . This little UAV is proven and used by a number of Navy’s around the World, even by the Russian coastguard. River B2 OPV already has “maximize the use of herself” as having the >300 days “sea-going days per year”. NOT anti Submarine operations since even a T31 is going to struggle to operate in that environment. It’s that last 10% that kills you cost wise (see T26). Napier can have no delays, and any money should go there. PREMIUM: Taiwan launches new corvette and commissions minelayer.
