Background
For Inyursta, control of their waters had always been a hot button issue. Ever since its inception in the early nineteenth century when the corrupt post-colonial elite pawned off usage of the Sea of Juarez to French and Spanish imperial forces keeping control of their continental territories in the western reaches had sovereign maritime control been a critical part of Inyurstan national identity.
The Cold War would bring conflict, disarray, subversion, counter-revolution and ultimately rebirth under the banner of neoliberal capitalism. With their new found independence and reborn identity, the military and government made it their goal to defend against the threat of Soviet warships and submarines returning to the nominally calm, tropical waters around Inyursta to rekindle the fires of socialism and leftist revolution. It was here, somewhere between ousting a pinko puppet regime and emerging into the 21st century a regional power, that La Républiqua D'Inyursta gained de-facto control of the seas around their nation.
Then, in 2018 Jean-Baptiste Calderone was elected on a platform of national security - but not just national security, de-jure reclamation of what was rightfully theirs. Calderone was one of the key players responsible for the inception and drafting of COSTAL.
The Convention for Stability, Armament and Liberation.
A modern Convention to replace outdated previous standards of national law.
Stability, to allow nations to keep warmongering and unwanted military incursions from their shores.
Armament, to give legal recognition to the right of navies, coastal defense and maritime law enforcement to unquestioned authority over that which they control.
Liberation, at last to give every nation that had been screwed over by imperialism and obsolete Western-centric conventions to take back what was theirs.
The antiquated twelve nautical mile limit would soon be dead, buried in the ages like the relic "cannot shot rule" it replaced.
Tides of Change were sweeping fast across the oceans, and Inyursta was one of the top nations riding them to their natural outcome...
Inyurstan Oceanic Territory, Present Day
On the surface, everything was calm and peaceful. Low waves of clear turquoise lapped across white sands, while leafy seagrass swayed with the surf like green strings suspended in a blue liquid crystal. Beach goers frolicked in the shallows while fishermen cast their lines far beyond the rocky coral reefs hugging the edges of the deeper waters.
The surface, was of course, deceiving.
Stowed away on land was the the multi-static Ramone Sarillo OTH system, with multiple arcs blanketing almost everything from 100-3,000km out, installed with several objectives in mind - one of them being the detection of incoming surface vessels. Stacked in sporadic but strategic locations were AShM and ASW batteries, and an almost equal number of decoys and mimics.
Down bellow the azure glass was equally poised for defense of the homeland and interdiction of unwanted intruders. A lethal but silent tag-team of Type-60 SSP's and the seafloor-based CCUSG kept an eye for underwater contacts.
High in the skies, maritime patrols of various types were the real eyes, the clarity behind the grand scene everything else. E-2D Hawkeye, Ka-64YE helicopters, along with IA-59 Cerícalo drones and ECN-235 ELINT aircraft did the bulk of the reconissance work.
Enemies of La Républiqua D'Inyursta and its democratic system were weak in number, but heavy in both arrogance and perseverance. Threats of quote "innocent passage" through rightful Inyurstan internal waters had turned up null (of course, how can anything be innocent if it is done in direct opposition to the popular will of the people who live there?), and the lack of any effective response had been a good sign for the battle of sovereignty vs imperialism, capitalist property rights versus socialist mandated sharing. It was only a matter of time before someone decided to make good on their threat to test what the Inyurstans could and could not do...
And as one of the leading nations in the post-colonial resurgence, the fastest developing nation in La América Libré and the primary drafter and signatory of COSTAL it would be up to them to beat any challenger back to where they belong...
