Put it in here, as we know Twitter guy is 'Euro' sales agent. Thus he will got hints on how 'Euro' sales project progressing. This tweet on Gas Turbines operational concern, as being put by some ex TNI-AL brass like Admiral Sondakh, shown 'still" the concern on how TNI-AL can afford the 'fuel' on those gas turbines frigattes with present trend of operational budgets.
Some rumours also talk on diesel engine thinking also influences why Indonesia choose ex Nahkoda Ragam light frigattes, rather offer on ex Type 22.
However with this indication money trail being prepared for Gas Turbines equip ex ROKN corvettes, shown also 'seperate' thinking on how to manage operational budget. Perhaps some think it is ok to operate gas turbines for 'interim' solution. Or even 'perhaps' the thinking (this is just my speculation), just get that corvettes cheap and 'rengined' them with Diesel later on.
The last one is not without precedent, as with TNI-AL services reengined already happening before. All six Van Speijk Frigates were reengined and convert from Steam Turbines to Diesels. It will be more changes needed on power design on converting gas turbines to diesels. However talk with some ship yard people (granted mostly civilian yards), converting any power pack in the ships from one form to another is possible.
If he's right on delaying FREMM executional contract, asside from budget allocation schedulle, could this also part of 'redesign' ? Afterall the Arrow 140 design are more or less 'tweek' by Babcock and PAL for those being prepared for manufactured in PAL. So who knows if similar thing happen on FREMM.
Just my two cents.
