The Free Navy is the self-styled naval military branch of a faction of the Outer Planets Alliance. Originally, it was formed from a student-led organization. Their members are sometimes viewed and/or referred to as "OPA extremists", especially by the incumbent OPA leader, Fred Johnson.


The Outer Planets Alliance, or OPA is not as unified and solid as many believe. The organization has become even more fractured as time goes on and as clear leadership is vied for. While Fred Johnson assumes the outward label of "leader" of the OPA, various cells and sub-factions have splintered off from the core OPA group. In addition to various small grass roots cells such as Far Horizons Foundation, a student led organization that came from the OPA, larger cells have emerged.

One such is the self titled "Free Navy". The creation of Naomi Nagata's ex-lover Marco Inaros, this cell of the OPA wants to focus on controlling the newly discovered gate system that has emerged at the edge of the Sol system.

"OPA Extremists", as Fred Johnson refers to them, led by Marco, the Free Navy has begun initiating pirate-like and even terrorist attacks against Mars and OPA held facilities. MCRN Callisto shipyards and Pallas were two particular targets of the Free Navy. Marco and his group fear, that the appearance of the gates (and thus travel to distant, habitable worlds) will cause the Belt region to fall into economic collapse.

The Belt was once the frontier and the destination of many travelers and thus held much influence in trading. With the gate in place and other worlds looking to be more highly desired realms of exploration, the Belt would be abandoned. In reaction to this, Marco channels his already established resentment of the Inners into the creation of the Free Navy.

The Free Navy begins strategically attacking targets and stealing ships, weapons, cargo, water, parts, and other supplies. Most alarmingly, ships begin to disappear on their way through the gate system. While the ratio isn't *too* high, enough of them begin to go missing that it raises some eyebrows. Some of the missing ships were indeed being captured, pirated, refitted, and re-purposed into the Free Navy's growing armada. They attempt to disperse the newly fitted and branded ships throughout different stations along the Belt.

Marco, on behalf of his Free Navy organization, delivers a threat/ultimatum to the Inner Planets. He officially declares, that Earth and Mars will be allowed to exist and govern themselves, but they must submit the gates to the Free Navy and will no longer have any jurisdiction over the Belt region.

Filip Inaros, the son of Marco Inaros and his former lover Naomi Nagata, is being groomed by his father to equally hate Earth, Mars, his mother, and the inner system. He plans to "inherit" the Free Navy organization. He has already participated in multiple attacks and raids and is soon on the run from Mars military.

In a brazen blitzkrieg of attacks, the Free Navy, which had slipped away with it's newly re-purposed and stolen cache of ships and equipment, successfully launch a near apocalyptic attack against Earth. They also strike against Mars in an assassination attempt against Nathan Smith,and Tycho Station, the corporate arm of the OPA. The strikes present themselves as a sort of declaration against all and comes with immediate shock from the big three organizations. The major attack, which involved launching and hurling asteroids down on Earth in a massive bombardment, was initiated and given the "go ahead" by Naomi's son Filip, who took major pride in the devastation.

During the final stages of their planned first attacks on the inner planets, the Free Navy's ship Chetzemoka is caught flatfooted, and is involved in a direct stand off with all the other major players. A U.N. escort fleet arrives, along with the Rocinante and Julie Mao's old racing skiff, the Razorback, which has Bobbie Draper and Alex Kamal aboard.

Marco Inaros and his Free Navy continue to wage a war against James Holden and Fred Johnson. There is growing doubt over charismatic leader's vision within the man's core organization, including Anderson Dawes and Michio Pa. Even more, his prince, Filip Inaros, is becoming disillusioned.

Marco has commissioned Michio Pa to capture inner planet colony ships headed through the gates with stockpiles of goods, which she is to redistribute to the Belt.

At the behest of the Consolidated Fleet, Bobbie Draper commands a mission for the Rocinante crew, now with Clarissa Mao, to disable the prospector ship Azure Dragon, which has been responsible for propelling asteroids on trajectories to slam into Earth. They are ambushed, as Bobbie becomes trapped in an airlock bridge while attempting to board the Free Navy ship. The Azure Dragon sends three mechs to strip the Rocinante in a surprise counterattack. Amos Burton and Clarissa risk their lives to rescue themselves and their shipmates.

The Free Navy abandons Ceres Station, Anderson Dawes' home and governorship, after Filip hospitalized a station peace keeper. To Michio Pa's chagrin, Marco Inaros orders not only the abandonment of Ceres, but other stations along with abandoning their commitment to feed the Belt.

Michio abandon's Marco and arranges a pact with Fred Johnson representing the Consolidated Fleet on Ceres. This allows safe passage while she distributes goods to Ceres.

As Fred Johnson once again attempts to unify OPA factions against Marco's Free Navy extremists, he organizes a meeting with OPA factions on Tycho Station. Marco leads an attack against Johnson and the enlarged crew of the Rocinante as they travel from Ceres to meet the others. Marco leaves Filip in weapons control. Fred Johnson manages to summon missile support from Ceres, which draws one of the pursuing attackers off the Rocinante. Alex and Bobbie manage to claim victory after a tense fight with the remaining two Free Navy ships, but not without Fred Johnson succumbing to a stroke.

At the alliance summit on Tycho, Holden and Bobbie plan a daring scheme unifying the inner planets with OPA to take Medina Station from Marco and the Free Navy.

Having obtained stealth technology deposits from corrupt officials of Mars, the Free Navy began collecting iron-nickel asteroids and coating them in these materials. These were then artifically accelerated and slung towards Earth.

When one of the asteroids broke apart by the gravitational pull of the Sol star it was spotted as a debris field by the science vessel UNS Hasami near Venus which moved to investigate. Unknown to the crew however a Free Navy gunship was following them. The gunship disabled Hasami and launched a boarding party. Once onboard the computer cores were removed and the crew executed. Afterwards missiles hit the science ship destroying it, removing any potential evidence for their activities. While individuals on Luna such as Chrisjen Avasarala suspected a potential danger from the Free Navy, the UN remained largely oblivious to Inaros' plans.

When the first asteroid reached Earth it remained completely undetected to planetary defences, making impact off West Africa. While the UN was quick to oganize humanitarian relief efforts and the senior government under Nancy Gao was evacuated on board UN One above South Asia, the second and third impact proved desastrous however. The initial impacts killed millions, while seismic activity and tsunamis devastated major cities on Earth, most notably New York City; most of the government and senior military infrastructure was presumed to have been eliminated with the attacks. However, it was possible for Avasarala to convince Gao to conenct the Sentinel asteroid spotters to the sensors of the Watchtower spy satellites as to penetrate the stealth coating of the remaining asteroid. With this method, three other asteroids were successfully destroyed before impact.

Simultaneously to the attacks on Earth, a presumably Free Navy terorist bombing plot was successfully conducted at the Parliament of the Martian Congressional Republic, with a yet unknown amount of casualties and damage. On Tycho Station, a hostile takeover of the last remaining Protomolecule sample and defection of numerous OPA and station staff led to the killing of Fred Johnson.

Subsequent to the row of attacks, Marco Inaros as figurehead of the Free Navy claimed responsibility to the attacks, setting its political and ideological demands to Earth and Mars and igniting the Free Navy Conflict.

The Razorback sights the Free Navy fleet

Investigating the theft of Martian military equipment Alex Kamal and Bobbie Draper took the unarmed racing pinnace Razorback out following at a distance the MCRN Barkeith and its two frigate escorts. They followed them towards the Hungaria group asteroids where they spotted them with Free Navy ships some of which were MCRN built and others Belter ships. At this point the Razorback was spotted and fired upon with a torpedo. The Pinnace attempted to flee at High-G but was forced to drop core to destroy the torpedo behind them.
