2-7 Laser Guidance System

The system enables weapons to acquire and track laser designated targets in real time and guide projectiles toward the reflected laser energy during the terminal guidance phase. It is designed as a scalable framework that can be integrated into a wide variety of weapon systems and expanded by other mod developers.

This system is currently used by the **2-7 Postradatelní mod ecosystem** and integrates with **WCS_Armaments**, but it was designed to remain modular and reusable for other weapon platforms.

Core Features:

Semi-Active Laser (SAL) Guidance
Implements realistic Semi-Active Laser homing where a projectile or missile tracks reflected laser energy from a designated target.

Supported guidance modes include:
- Continuous laser designation
- Terminal laser acquisition
- Dynamic mid-flight target tracking

Weapons equipped with the system guide toward an active laser spot generated by a designator using a configurable laser code.

Laser Target Designation

Targets can be designated using a laser designator capable of generating and updating laser spots in real time.

Supported designation methods:

Live Laser Designation
- Continuous target illumination
- Real-time updates of laser spot position
- Dynamic tracking of moving targets

Pin-Point Target Marking
- Static laser target coordinates
- Persistent designation markers
- Suitable for artillery or precision strikes

Multiple designators can operate simultaneously in the environment.

Configurable Laser Codes

The system supports standard NATO laser codes used by SAL guided weapons.

Features include:
- Customizable laser code assignment
- Code matching between designator and munition seeker
- Multiple simultaneous designation channels
- Code filtering for target acquisition

Weapons only track laser spots matching their configured code.

Target Acquisition and Lock Logic

The seeker behavior is configurable and includes:
- Field-of-View limitations
- Lock-on angle constraints
- Maximum acquisition distance
- Prioritization of multiple laser spots
- Dynamic target selection based on geometry

This allows realistic SAL terminal guidance behavior.

Environmental Countermeasures

Laser designation can be disrupted by battlefield conditions.

Smoke Obscuration
- Smoke clouds block laser designation
- Laser spots inside smoke become occluded
- Guided munitions lose tracking on obscured targets

GPS Guided Navigation

The system now also supports **GPS-guided rocket navigation**.

Features include:
- Autonomous navigation to target coordinates
- No laser designation required
- Designed for precision strike rockets

Currently this functionality is implemented for **NATO-type guided rockets**.
Russian GPS / GLONASS weapon variants are planned for future updates.

Helicopter Laser Guidance Modes

Helicopter launched SAL missiles support multiple laser targeting modes.

Laser Mode OFF
- Default WCS seeker behavior
- No P27 designation logic applied

Laser Mode SELF
- Helicopter gunner designates the target using onboard optics
- Real-time laser marker generation

Laser Mode JTAC
- Missile searches for externally generated laser spots
- Enables cooperation with JTAC units or ground designators

This logic is currently implemented for missiles such as:
- AGM-65 Maverick
- Kh-25 (from 2-7 Vehicle Modification mod)

Modular Architecture

The system was designed as a modular framework that can easily be integrated into additional weapon systems.

Current and potential integrations include:
- Laser-guided artillery shells (Copperhead type)
- Laser-guided rockets
- Laser-guided missiles
- GPS-guided rockets

Other modders can attach SAL or GPS guidance behavior to their own projectiles.

Integration with WCS_Armaments

The system integrates with **WCS_Armaments**, allowing advanced weapon platforms to use precision guided munitions within a unified framework.

2-7 Helicopter Modification

Helicopter laser guidance features are currently used by the **2-7 Helicopter Modification** package.

This mod provides helicopter weapon systems and optics used by the Maverick and Kh-25 implementations.

However, the **laser guidance framework itself has no hard dependency on this mod**, allowing other modders to integrate the system into their own aircraft or weapon platforms.

Designed for Modders

The **2-7 Laser Guidance System** serves as a foundation for future guided weapon systems in the community.

Modders can use the framework to implement:
- Laser guided projectiles
- GPS guided weapons
- Laser designators
- Target acquisition logic
- Environmental countermeasures

The system was built with scalability, modularity and realism in mind.
