Royal Nusantara Navy 1922-1946:
General Information:
The following is an overview of warships of the Koninklijke Nusantara Marine (Royal Nusantara Navy) from the signing of the Washington Naval Treaty to the end of the conflict with Imperial Japan during World War II.
Background to 1922:
The naval arms race between the Dominion of Nusantara and the Japanese Empire began at the turn of the Twentieth Century following the victory of Japan in the Russo-Japanese War (1904-1905). It was quickly realized by the Navy Ministry and the KNM Admiralty that there was now a formidable new opponent in the Far East and the country wasn’t prepared.
Since its founding in 1820, Nusantara had maintained a navy, but it was small compared to the Great Powers of Europe as there were no neighboring nations posing a threat and the country was on good terms with the home country; the Netherlands, as well as the UK. In the latter half of the Nineteenth Century, relations grew with the US, and Germany following the latter’s unification in 1871, and by 1900, a number of the KNM’s ships had been built in foreign shipyards and most of Nusantara’s heavy weapons were purchased from overseas as well.
To counter the Japanese buildup prior to the war with Russia, Nusantara had embarked on a building program focused on battleships, including the first indigenously designed and built examples. By 1908, the pre-dreadnoughts of the
Marapi (3),
Semeru (2) and
Hiri (2) classes had commissioned. In addition, two new armored cruisers of the
Bengkulu class had entered service by the end of 1911.
But by then, the launch of the revolutionary HMS
Dreadnought in 1906 and HMS
Invincible – the world’s first battlecruiser a year later – had changed everything.
Nusantara’s first modern capital ships were the
Toba (2) and
Kerinci (3) classes which, although well-armed and armored for their time, were still somewhat inferior to their Japanese contemporaries. The next class of battleships, however, would have equaled their potential opponents – even the powerful
Nagato class, both of which had been launched by 1920. The six
Lewotobi class “super-dreadnoughts” were laid down in 1921 as a direct response to the newest Japanese battleships. In addition, a new class of battlecruiser to supplement the
Toba class was planned for 1922-23.
This large (and expensive) building program, although not directly part of it, paralleled a new naval arms race among the victors of the Great War. The US, UK, and Japan had all embarked on massive new programs by 1920, which were cut short by the Washington Navel Conference of November, 1921.
Intended to curtail the rising costs of these programs as well as “level the playing field” for capital ships, the conference was called by the US to be held in Washington DC. The original invitees were the UK, Japan, France, and Italy – together with the host country the five largest navies in the world. Japan, recognizing an opportunity, insisted on inviting Nusantara as well, hoping to hobble this potential rival for the foreseeable future.
Although the resulting treaty established limits on numbers, displacement and armament for capital ships for all signatories, Japan’s delegation came away angered by the inferior build ratio they received compared to the US and UK, which they had lobbied for equality with.
Also, they were disappointed with Nusantara’s terms – which not only gave them a better ratio – between Japan and France/Italy – than Japan had wanted, but also allowed them to complete four of the
Lewotobi class battleships then under construction, and convert the remaining two hulls into aircraft carriers in order to come up to treaty limits.
And although Japan would abide by the terms of the Washington Naval Treaty for the most part, it chaffed under its restrictions, eventually abandoning the Treaty around 1935 – ironically triggering another arms race with Nusantara in the years leading up to the outbreak of war in July of 1941.
