"FIREFLY" High-speed scout submarine of the tier 2

[hr][/hr] • Price: 10,599 mk • Sizes: 24x6 • Cargo: 4 • Crew: 3-5 (designed for 3) • [bMaximum speed: 40 km/h[/b]

[hr][/hr] Door system: The red button below the main button allows you to lock the door (this function is only available to the captain and security personnel). If the main button is lit blue, it means that the compartment is flooded. If it is lit orange, it means there is a fire in the compartment.

Valve and pipe system: In the event of pipe failure, the flow must be shut off using special valves. The valve in the oxygen generator allows the air to be shut off.

Switches and levers on the sonar monitor: Two adjacent levers with blue lamps drain the ballast. A separate lever is responsible for activating the manual alarm. Two switches are responsible for the operation of the lights.

Alarm system: The alarm is triggered by fire, flooding, and close contact with the external ecosystem. Personally, the cap triggers an alarm, which indicates that Burst mode is working. A manual alarm is provided.

Other: The monitors above the sonar display the amount of fuel, oxygen, and battery charge. It has a backup power supply in the form of a battery that supports the main one in case of shortage. The reactor emits radiation due to its special assembly, be careful! (if you are using a mod that increases the radius of an unstable rod, then you will have to go into the editor and delete it)

[hr][/hr] The submarine is equipped with a terminal where its systems are configured for specific tasks:

• Normal mode - Everything is functioning as it should.

• Stealth mode - The external lights turn off, the submarine's movement and reactor are weakened, and the batteries and fabricators are not working.

• Burst mode - The engine is running at full power and the reactor is overloaded (any reduction in the network load will cause a breakdown), the batteries and fabricators are not working.

• Eco mode - Almost everything is operating at full capacity, which significantly conserves reactor fuel.

[hr][/hr] The Firefly submarine was designed by naval architects as a cheap and small vessel for military reconnaissance at station boundaries, as well as for patrolling the surrounding area, for further pursuit, or for urgent communication. The submarine is a high-speed second-class reconnaissance vessel capable of covert navigation. It was designed for a small crew of three people.
