Introduction to BVR Combat Systems

Introduction to BVR Combat

• Addition of Beyond Visual Range (BVR) systems enhances lethality and complexity of combat missions.
• Controllers and pilots form a supportive team, sharing information and strategies.
• Controller's effectiveness varies based on their situational awareness (SA) and understanding of pilot tactics during BVR engagement.

Important Terms for BVR Combat

• Understanding key terminologies related to BVR combat is crucial for effective engagement strategies.

Classification of BVR Missiles

• BVR missiles are generally categorized into two types:
  • Semi Active Radar Homing (SARH)
  • Active Radar Homing (ARH)

Semi Active Radar Homing (SARH) Missiles

• SARH missiles feature a passive homing seeker head.
• Initially guided by inertial navigation, the missile receives mid-course corrections via radio commands.
• During the terminal phase, the missile transitions to a semi-active radar homing mode.
• The launching aircraft illuminates the target with continuous wave radar to guide the missile to impact.
• If the launch aircraft loses radar track (due to maneuvers, loss of lock, or jamming), the missile is rendered ineffective.

Introduction to BVR Combat

• Integration of Beyond Visual Range (BVR) weapons enhances lethality while complicating combat missions.
• Controllers and pilots function as a cohesive team, sharing access to various information sources.
• Effective BVR operations require controllers to deeply understand pilot tactics and techniques.

Important Terms for BVR Combat

• Recognition of basic terminology is crucial for understanding BVR employment.

Classification of BVR Missiles

• BVR missiles categorized into two primary types:
  • Semi-Active Radar Homing (SARH)
  • Active Radar Homing (ARH)

Semi-Active Radar Homing (SARH) Missiles

• Utilize a passive homing seeker head for target tracking.
• Initially guided by inertial guidance, transitioning to semi-active radar homing during the final flight stage.
• Requires continuous illumination of the target by the launching aircraft until the missile reaches impact.
• Loss of radar track (due to maneuvers, break locks, or jamming) results in missile failure.

Active Radar Homing (ARH) Missiles

• Operate independently after launch, allowing the launch aircraft to disengage from the target.
• Capable of "fire and forget" operations, improving tactical flexibility.
• After launch, missiles self-navigate, with corrections based on data links from the parent aircraft initially.
• Reduced reliance on parent aircraft’s radar creates a larger search volume and opportunistic targeting.

Strengths of ARH Missiles

• Ability to operate as "fire and forget" once they achieve a designated target tracking point.
• Facilitate multiple target engagements thanks to advanced tracking capabilities.
• Allows the launch aircraft to maintain situational awareness in the operational area while the missile engages targets.

Limitations of ARH Missiles

• Mono-pulse radars in active seekers may lose lock on highly maneuverable targets.
• Smaller active seekers are vulnerable to electronic countermeasures during terminal phases.
• Data link interruptions before reaching the target acquisition point can significantly decrease the probability of kill (Pk) for the missile.
• Modern BVR systems integrate advanced electronic countermeasures to mitigate these limitations.
