HIMS Nargun, third of a quartet of battleships designed on the assumption that the naval arms limitation treaties would not long survive the resumption of warship construction. The outbreak of the long-awaited war to the knife with the Empire Japan less than a year after they were laid down proved this correct. Four dual 42cm guns, backed by a dual purpose battery of 12cm guns. Service speed of 32 knots, armor based on that of the N3, somewhat modernized. Radars are those fitted in the United Kingdom upon her arrival in the spring of 1942 after initial working up in home waters. Based at Scapa Flow with her sister ship Eingana until the duo returned home for a major refit in early 1943, having served to help hold the line against the combined German/Spanish/Lavalist forces.

She's a very pretty battleship!

Impressive drawing for sure.

Big and beefy and attractive, although I can't shake the feeling that she looks very wet forward.

The portholes also seem sort of incongruous with her era.

She has about three feet less freeboard at the stem than Iowa, with more hydrodynamic 'lift' to her bow, but I suppose some wetness at speed will be expected without more sheer.

As to the portholes, they're still present on most European designs of the period, at least on the upper parts of the soft ends, with only the US having gone so far to remove them completely.

These ships had their genesis in the relentless French building programme in the wake of the Franco-Prussian war and 'The Seventy-Three' between Aururia and France. Six Dantons gave way to six ships... and six more... and six more after that. With the Entente Cordiale at least somewhat guaranteeing France could afford to send most of them to Cam Ranh Bay, the Empire's concern as the moment of 'maximum danger' seemed to approach steadily grew. Casting about for ships, first came the Brazilian Rio. Her design was intensely unsatisfactory, but she was available - and that was enough. She could be refitted later. The Argentines bowed to American pressure and refused to sell their dreadnoughts - much the same for Chile, whose would be delivered too late anyhow. With the 1914 programme fixed at four ships, the government turned to Vickers-Kaurna, who turned to their corporate parent, still closely wedded at this point in history - specifications were ready, and a premium paid to return the sketch designs quickly. They would not be fully acceptable ships, but they would do. They had to. The contracts were signed, and the delivery date set for twenty-four months. Six and a half million pounds was paid for the two ships, a crushing burden for the time. Then an Archduke was shot down in Bosnia, and the two most powerful ships building in Britain became an even more tempting target for the Royal Navy. There was a purchase option in the contract, but it laid a stiff price. The full cost of the two ships and the broker's commission, to be paid in gold, in addition to a usage fee for as long as they remained in British service. With the German invasion of France, the government in Mayi-Thakurti was willing to sell, on the condition that they would have the right of repurchase as soon as a peace was signed. With the armour, turrets, and guns already ordered, they could complete without further throwing chaos into the British warship building programme - and they promised a counterbalance to rumours of new German battlecruisers.

Both ships missed Jutland, joining the Battlecruiser Fleet not long afterwards, having been converted to oil fuel under Fisher's influence, each touching 29 knots during abbreviated wartime trials. Their war service left them run-down as 1919 rolled around, but they had escaped being exposed to enemy fire but for the ever-present danger of U-Boats and mines.

As soon as Versailles was signed, locked into a new building race with the Japanese and Americans, the amazons returned, wanting their two ships back. Paying the agreed upon price, they had effectively made a profit on a pair of battleships, though the conversion from coal to oil fuel had left them intensely cross at what had been done. They joined their intended fleet under their names as commissioned, for they were amenable to the lower deck, and there was no need to risk ill omens by a re-naming, as was sometimes necessary for foreign commissions.

The last foreign-built vessels for the Imperial Navy until the Zubr types, they were regarded as being satisfactory ships in every respect, serving as the core of the battle-line alongside their home-built half-sisters of the Silver Sea class until after the Great Pacific War.

Drawing is nice.

For diplomatic reason, I don't think you should use the name ISIS. So I recommend you to change the name very fast.

Well, I would suppose we might all be smart enough to know that first and foremost, Isis was her:
https://en.wikipedia.org/wiki/Isis

Isis is the female, her brother, and husband is Osiris.

So an AU about Nazi Germany, probably the objectively most evil regime in modern history, or the CSA, who fought for chattel slavery, is okay but an au where one design shares a name with a terrorist organization is crossing the line?
