ARCA has yet to launch a vehicle above the Karman line, or sent a payload to orbit, with the majority of their projects having been abandoned due to various reasons, often including financial or regulatory constraints.

[3] In 2003 ARCA also signed up for the Ansari X Prize international competition and started design for the Orizont suborbital vehicle capable of carrying a crew of two up to an altitude of 100 km (62 mi).

Because of financial problems encountered with the construction of Orizont, ARCA decided to suspend its development and instead design a new, much smaller rocket called Stabilo.

The mission was launched from Cape Midia Air Force Base, and the rocket was recovered from the Black Sea surface by Romanian Navy divers.

Romanian cosmonaut Dumitru Prunariu highly praised ARCA's achievements and noted their ability to efficiently utilize private funds.

Three hours later the arms were repositioned and inflation was ready to resume but the sun was already nearing the horizon, and heating the solar balloon was no longer possible.

On August 4, 2010, a new attempt to launch the rocket was made, but a construction error in the helium balloon caused it to rupture and the mission was aborted.

[15] After the difficulties encountered with the stratospheric balloons, ARCA decided to change their approach to orbital launch for the Google Lunar X Prize.

It uses ablative cooling for the main chamber and nozzle where the outer layers of the composite material vaporize in contact with the high temperature exhaust mixture and prevent overheating.

ARCA mentioned that the Romanian Space Agency is in no position to criticize after the failure of their cubesat Goliat recently launched with a Vega rocket.

[21] On September 16, 2013, ARCA performed the first successful flight in the ExoMars program, lifting three pressurised avionics containers over the Black Sea to an altitude of 24,400 m.[22] In November, the concrete test stand for the Executor engine was completed.

On February 10 ARCA presented a high-altitude uncrewed aerial vehicle, named AirStrato, that was meant to replace stratospheric balloon usage for equipment testing and other near space missions.

On July 13, 2015 ARCA announced the beginning of activities in New Mexico, including production and flight tests of AirStrato UAS and Haas rockets, investing US$1.2 million.

In 2022, ARCA announced the AMi Exploration Initiative, effectively pivoting its business model away from the commercial launch sector and towards cryptocurrency and asteroid mining.

Beginning in the late 2020s, the company plans to start a series of asteroid mining missions to return valuable metals (mostly platinum) to Earth for sale.

[30] At the NASA DC-X conference in Alamogordo, New Mexico in August 2013 ARCA presented an updated version of the Haas 2B rocket with a capsule capable of carrying a crew of five into space.

The mission took place in cooperation with the Special Aviation Unit and the Coast Guard, belonging to the Ministry of Internal Affairs and Administration.

Each stage will consist of multiple "propulsion modules" attached together, which the CEO Popescu describes as being inspired by the now-defunct German launch company OTRAG.

The basic premise and interception method of the vehicle consists of a 6-10 metric ton device (referred to as the “warhead”) carrying between 200,000-2,000,000 metal pellets, chaff, and flares, all of which are “electromechanically” deployed.

While the organization’s main focus remains on the development of the EcoRocket orbital launchers, they have begun work on several other systems, in order to generate technical data and revenue for the AMi program’s hardware.

Executor was an open cycle gas generator rocket engine, that uses liquid oxygen and kerosene and has a maximum thrust of 24 tons force.

The phenolic resin reinforced with silica fiber pyrolyzes endothermally in the combustion chamber walls, releasing gases like oxygen and hydrogen, leaving a local carbon matrix.

The LAS was proposed to be a first stage for the Haas 2CA rocket, or to serve as a strap-on booster for existing vehicles, including the Atlas V, Falcon 9, Delta IV, and Ariane 6.

After one hour and 30 minutes and having traveled 30 km (19 mi) from the launch location, STABILO landed on the sea surface and was intercepted by a Navy Saturn ship and recovered by divers.

The maximum distance between the carrier balloon and the command center at Sanpetru airfield was 42 km (26 mi), which corresponded with the Helen 2 rocket simulated safety zone.

The balloon crew was composed of Mihai Ilie – pilot, Mugurel Ionescu – copilot, and Dumitru Popescu – ELL equipment operator.

When the containers reached an altitude of 24.4 km (15.2 mi), they were released under a dedicated recovery parachute and landed on the sea twenty minutes later.

This mission has apparently been scrapped, however, ARCA completed a short, low-altitude flight of the EcoRocket Demonstrator's second stage in the fall of 2021 with no landing attempt to test the RCS systems aboard the rocket.

The test validated the canister exist sequence of the CER-160TR artillery target rocket, in a similar manner to the silo exit of a missile or interceptor.

Mission 13 was a launch of the LAS-1 rocket from an ARCA-built water tower, to validate and assess the performance of the engine’s start and thrust while submerged.
