L-39C

Sign in to edit

The L-39C is a jet trainer used exclusively by the Czech military in ArmA 2. It was added with the release of the Army of the Czech Republic DLC.

Overview[]

  • Role:
    • Flight training

Design[]

Premium content logo
This is a premium asset that requires ownership of the Army of the Czech Republic DLC.

The L-39C is a jet trainer derivative of the L-39ZA light attack jet. Unlike its parent aircraft, the L-39C is designed exclusively to train pilots and is therefore completely unarmed (its wing hardpoints and 23 mm autocannon have been removed).

Features
The only differences with the L-39C compared to the L-39ZA is its lack of armament, defensive countermeasure dispensers, and unique light grey camouflage scheme. Aside from these changes, the L-39C shares the same flight envelope with the L-39ZA and can attain a top speed of up to ~ 631 km/h in level flight.

Crew Capacity
The L-39C only contains a single seat for the pilot. It is unable to transport any passengers or crewmen.

L-39ZA[]

Protection: Hitpoints[]

The L-39C has a base armour value of 60.[CfgVh 4]

Hull[]

The L-39C's hull can only take up to 60 points of damage before its integrity fails.[CfgVh 5][Formula 1] Depletion of the hull's integrity will instantly result in its destruction.[CfgVh 6]

The L-39C's airframe utilises a mix of armour plates, plain metals, and plexiglass:

  • The landing gears are protected by armour plates that have a thickness of 5 millimetres.[rvmat 1][bisurf 1]
  • The L-39C's vertical tail and both of its wings are protected by armour plates. These plates have a thickness of 7 millimetres.[rvmat 2][bisurf 2]
  • The rear section of the L-39C's fuselage (including the engine) is protected by armour plates that have a thickness of 11 millimetres.[rvmat 3][bisurf 3] This also includes the front-left side of the cockpit canopy, which isn't actually made out of glass but is protected by a rectangular-shaped 11 mm armour plate.
  • The frontal half of the fuselage, nose, and cockpit are protected by armour plates that have a thickness of 23 millimetres.[rvmat 4][bisurf 4]
  • The semi-circular air intakes are made out of iron.[rvmat 5][bisurf 5]
  • The base of the vertical tail is made out of plates of plain metal. Its metal plates have a thickness of 2 millimetres.[rvmat 6][bisurf 6]
  • The cockpit's canopy is mostly made out of panes of (non-bullet resistant) plexiglass that have a thickness of 2 millimetres.[rvmat 7][bisurf 7] Only the front-right section of the canopy is specifically protected by a pane of bullet-resistant glass.[rvmat 8][bisurf 8]

It should be noted that the cockpit canopy is not fully bullet-resistant. Only the front right section of the canopy window is actually bullet-resistant and is capable of blocking small arms fire from calibres up to and including 7.62 mm (12.7 mm/.50 cal bullets can still penetrate these windows). The other cockpit windows (side/top) cannot block bullet projectiles at all as they are not made out of bullet-resistant glass.

Avionics[]

MAWS[]

The L-39C is fitted with a Missile Approach Warning System. The MAWS will automatically warn the pilot if a guided projectile has successfully locked onto the jet and is inbound towards it.[CfgVh 7]

RWR[]

The L-39C possesses a Radar Warning Receiver. It will alert the pilot if the jet is being locked onto by radar-based targeting system.[CfgVh 8]

IWR[]

The L-39C is not equipped with an Infrared Warning Receiver. The pilot will not be warned if an infrared-based targeting system is attempting to acquire a lock onto the jet.[CfgVh 8]

LWR[]

The L-39C has a Laser Warning Receiver installed. It will warn the pilot if they are being locked onto by a laser-based targeting system.[CfgVh 8]

AI[]

NOTE: The following information only applies to the AI.

Camouflage rating[]

Main article: AI Basics: Detection

The L-39C has a camouflage[3] rating of 100.[CfgVh 9]

Cost[]

Main article: AI Basics: Targeting priority

The L-39C has a cost[4] value of 2000000.[CfgVh 10]

Threat values[]

Main article: AI Basics: Targeting priority

The L-39C is considered to be an extremely dangerous threat[5] to AI-controlled ground vehicles (1).[CfgVh 11] The AI will always prioritise attacking the L-39C if they have the means to do so.

On the other hand, infantry and other aircraft only consider the L-39C to be a high-risk threat (0.7/0.8).[CfgVh 11]

Noise factor[]

Main article: AI Basics: Detection

The L-39C has an audible[6] factor of 20.[CfgVh 12]

Trivia[]

  • To date, ArmA 2's L-39C remains as the only dedicated jet trainer aircraft in the entire series.
  • Prior to the latest Steam version patches (as part of CorePatch's changes), the L-39C did not have access to defensive avionics. CorePatch subsequently changed this by enabling its MAWS, LWR, and RWR.[7]
