The Very Based and Missilepilled of UIS Leviathan is a gargantuan, cultured nation, ruled by Admiral Spriggs with an iron fist, and renowned for its compulsory military service, ubiquitous missile silos, and enslaved workforce. The hard-nosed, hard-working, cynical population of 14.931 billion UIN Sailors are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The relatively small, corrupt, well-organized government is primarily concerned with Defense, with Law & Order and Administration also on the agenda, while International Aid and Welfare are ignored. It meets to discuss matters of state in the capital city of The Rig. Citizens pay a flat income tax of 14.3%.

The strong a UIN Sailor economy, worth a remarkable 1,070 trillion 8 inch Guided Munitions a year, is fairly diversified and led by the Arms Manufacturing industry, with significant contributions from Information Technology, Uranium Mining, and Pizza Delivery. Average income is 71,705 8 inch Guided Munitions, but there is a significant disparity between incomes, with the richest 10% of citizens earning 234,658 per year while the poor average 16,461, a ratio of 14.3 to 1.

Citizens wouldn't recognise Admiral Spriggs if they passed one another on the street, the commercialisation of highly deadly weapons has instilled UIS Leviathan with a very polite populace, much of UIS Leviathan's computer network is controlled by a rampant artificial intelligence, and engine room hooch is the drink of choice among the nation's navy. Crime, especially youth-related, is well under control, thanks to a capable police force. UIS Leviathan's national animal is the Abomination Amalgam of Sin.

UIS Leviathan is ranked 279,647^th in the world and 32^nd in The United Islands of the Atlantic for Highest Foreign Aid Spending, scoring -13.42 on the Clooney Contribution Index.
