Abeg naval guys, what are the characteristics of NNS Thunder? Does it outclass ARADU?

NNS Aradu was purpose built for power projection and image reckoning by Shagari administration in 1980- it was equipped with good sensors, torpedoes, radars and mid range missiles( ship to air and anti shipping missiles) considered fit for this purpose. There has been news on refit (not confirmed by the navy) and the present state of the ship itself, its radars, sensors, missile systems is unclear. NNS Thunder (ex-Cutter chase) was a second hand dash from US and customized for fit the operation intended for; which is primarily ant-piracy and sea patrol. It was stripped of bulk of its advanced radar and satcoms( it won’t be of any use to the NN anyway since it surely tailor made for US military). It is not clear whether any additional stuff were installed during the $8m refit. Definitely this amount would not be enough to include anti- shipping missiles, air to air missiles and very modern radars, FCS.

Armament wise, Aradu if refitted and upgraded is far better and also a bit faster even though it’s a bit heavier and larger.
Engine wise and maintainability: this is complicated-too many factors are at play here
Trying to compare Aradu with Thunder is not really comparing apple for apple, there purpose and history is quite different.
