Ainda não passa de conversas exploratórias, mas lá que era engraçado era (e já agora, mais 32 ESSM por navio a acompanhar)...
De notar que o radar referido é "surface search", não tem nada a ver com os ESSM.
New owners mull M-class frigate upgrades
Dutch efforts to generate funding for new ocean-going patrol vessels and a joint support ship, by selling-off six of eight 1990-built M-class frigates to other navies, are beginning to have an additional effect: new export opportunities for the Netherlands-based naval combat systems industry.
Chile, Belgium and Portugal have each signed for two of the relatively young, 3,300-ton M-class ships that were originally built by Damen Group-owned Schelde Naval Shipbuilding. Chile already operates its first M-class frigate with the second to follow shortly. At the end of March, the first ship for Belgium was officially commissioned -- the former HrMs Karel Doorman becoming the new BNS King Leopold I.
Meanwhile, the Netherlands defense ministry has announced a plan to upgrade the operational capabilities of the two M-frigates it plans to retain. Specifically mentioned is the new Seastar advanced surface search radar under development by Thales Nederland. Along with another new Thales radar, the air search-capable Smile S-band system, the Seastar is also a candidate to equip the Royal Netherlands Navy's new patrol vessels.
It is now being hoped that Belgium will join the M-class frigate upgrade program, all the more because the two Belgian ships will continue to operate from the Dutch Navy's homeport at Den Helder as part of the two nations' combined naval task group. Discussions with Chile and Portugal have also started. If the new owners go for the Dutch pitch, M-class ships in four different navies, as well as the new Dutch navy ships, will receive an attractively-priced (thanks to economies of scale) Seastar radar suite. According to Thales, Seastar is to be a staring-array X-band system optimized to detect small-sized asymmetric threats and periscope-type targets even in choppy seas.
A derivative of Thales' Gatekeeper electro-optical 360-degree surface surveillance system for force protection in littoral waters and inside harbors may also be installed.

Boa tarde!
De notar que o radar referido é "surface search", não tem nada a ver com os ESSM.
Podem confirmar-me se o radar à "medida" para o ESSM é o SEAPHAR? O tal que pode ser instalado em navios até aprox. 4000t, nomeadamente fragatas Meko e classe M, se abundassem "aereos"?
Cumprimentos!

Peço desculpa não ter directamente a haver com o tópico. Alguém sabe onde posso encontrar informação sobre RADAR LPI, já procurei e tá escasso.

Mais especificamente o quê?
O que é o LPI e como funciona? Ou caracteristicas técnicas (coisas como velocidade de salto de frequência, larguras de bandas utilizadas, etc)?
A definição de LPI é esta:
Low probability of intercept (LPI) is that property of an emitter that because of its low power, wide bandwidth, frequency variability, or other design attributes, makes it difficult to be detected or identified by means of passive intercept devices such as radar warning, electronic support and electronic intelligence receivers.
De qualquer forma creio que vale a pena ler estes PDF´s:

O que pretendo é mais como funciona. O segundo pdf não conhecia.
MUITO OBRIGADO SINTRA
