Se estes três NPO's custarem 20 Milhões, ou menos ainda vamos ás compras
Deve ser a compra ideal para a nossa MdG, armamento principal uma 20mm, não possuem flight deck, nem hangar para o Heli, mas podem transportar equipamento mais pesado pois tem uma grua de 25 tons........
No entanto se apontarmos as batarias para o HMS Clyde, bem esse seria um possível mini LPD, podendo transportar 110 militares + crew e o flight deck pode operar um EH101, portanto fica mais baratinho.
Os quatro primeiros River's entraram ao serviço entre 2003 e 2007 !

Tyne, Severn and Mersey[edit]
In early 2001, the Ministry of Defence placed an order with Vosper Thornycroft (VT) for three River-class offshore patrol vessels to replace the Island class.[2] It was understood that the higher availability rates of the River class (up to 300 days per year), would enable the three new ships to perform the duties of the five ships they replaced.
The Royal Navy initially chartered (or leased) the ships under a five-year, £60 million contract from the builder VT.[2] As part of the contract, VT would be responsible for all maintenance and support during the charter period. This contract was renewed in January 2007 for another five years at £52 million.[2] However,
in September 2012, instead of renewing the contract again, it was announced by the Defence Secretary Philip Hammond that
the Ministry of Defence had purchased the vessels for £39 million.[2][10]
The River class are significantly larger than the Island-class vessels and have a large open deck aft allowing them to be fitted with equipment for a specific role, which can include fire-fighting, disaster relief and anti-pollution work. For
this purpose, a 25 tonne capacity crane is fitted. In addition,
the deck is strong enough for the transport of various tracked and wheeled light vehicles, or an LCVP. The class are primarily used with the Fishery Protection Squadron and EEZ patrol.[2]
In 2009, the running costs for the River class was estimated at £20 million: "The average running cost... of [the] River class is £20 million... These figures, based on the expenditure incurred by the Ministry of Defence in 2009–10, include maintenance, safety certification, military upgrades, manpower, inventory, satellite communication, fuel costs and depreciation."[11]
Clyde
In February 2005, the Ministry of Defence placed an order with VT for the charter of a fourth modified River-class offshore patrol vessel.[2] This fourth ship, Clyde, was constructed at Portsmouth Dockyard and replaced the two Castle-class patrol vessels for duties around the South Atlantic and the Falkland Islands. To fulfill this role, Clyde incorporates several modifications, including an extended length 81.5 m (267 ft 5 in) hull, a top speed of 21 kn (39 km/h),
a 30 mm cannon, two miniguns and mountings for five general purpose machine guns.[2]
Clyde's elongated hull permits a 20-metre strengthened flight deck able to accommodate a Merlin-sized helicopter. The ship has a full load displacement between 1,850[2] and 2,000 tonnes.[12][13]
Clyde is capable of temporarily embarking up to 110 troops and their equipment and inserting them anywhere on the Falkland Islands.[2] Clyde has a complement of 36.[2]
Disposal
On 24 April 2017, in a written answer to a question raised by Sir Nicholas Soames, Parliamentary Under-Secretary for Defence Harriet Baldwin stated Severn would be decommissioned in 2017, with Mersey and Clyde following in 2019.[14] As of April 2017, no date has been given Tyne's decommissioning.
