SPECIAL FEATURES

• Recoil Mitigation Systems: Built-in compensators and inertial dampeners, coupled with kinetic absorption technology aides in keeping the recoil to a minimum.
• Adaptable: Can be adapted for built-in migration, or dual-battery, quad battery deployment.
• Targeting Systems:
  
  • Multiband tracking radar
  • Spectral sensor fusion (thermal, EM, gravimetric)
  • Limited target learning AI (non-sentient)
  • Pulse Lag Echo Compensation
    Signal-Layered Friend/Foe Discrimination
• Integrated Hypervelocity Rotary Gun System – Fires 20mm high-velocity depleted baradium shells in close-range automated bursts; capable of high-rate saturation fire.
• 20mm Depleted Baradium Casing/Slugs:
  
  • AP-DS Sabot Rounds: Hypervelocity Armor-Piercing, Discarding Sabot – Penetrates hardened targets with extreme kinetic force.
  • Baradium “Confetti” Rounds: Airburst Baradium-Tipped Shells – Detonate near targets, showering high-velocity fragments; effective against swarms and light armor.
  • Kastiel AMV Smart Rounds (Variable Payload): Modular rounds with internal programming to switch based on threat profile:
    
    • Penetrator (AP-DS) – Same as above; armor-piercing.
    • Fragmentation – Area denial or soft-target neutralization.
    • EMP/Ion – Electronics disruption, anti-droid, and shield interference.
  • Magpulse Rounds: Depleted Baradium Shell + Plasma-Proton Core – Surrounded by an ion sheath to weaken shields and destabilize systems pre-impact.
  • Depleted Baradium Slugs: Dense kinetic rounds used for sustained fire; punch through structure and armor via mass and speed alone.
• Ion Envelope Generator – Ionizes projectiles upon exit, enabling limited penetration through shielding and disruption of nearby electronics on impact.
• Programmable Detonation Fuze – Enables smart detonation modes including proximity airburst, impact, and delayed armor-piercing penetration.
• Fragmentation Nose Cap Selector – Randomly selected rounds are fitted with high-velocity frag noses to saturate the intercept zone with shrapnel.
• Fire-Control Integration – Works in tandem with the ship's targeting suite or SIGINT suite for rapid-fire prioritization of incoming missiles, torpedoes, or small craft.
• Anti-Stealth Pulse Interlace – Fires bursts that carry magnetic signature-interrogation pulses to detect and disrupt low-profile stealth craft or decoys.
• Overheat Shunt & Cooling Loop – Includes active coolant cycling to prevent weapon degradation during prolonged engagements.

STRENGTHS

• Multi-Role Defense: Handles warheads, drones, boarding pods, and even low-flying starfighters with adaptable munition profiles.
• Ion-Enhanced Kinetics: Each round passes through an integrated ion sheath, allowing kinetic slugs to better bypass shields or disrupt electronics.
• Baradium Payload Options: Baradium-tipped fragmentation shells offer high-explosive defense, causing cluster-style airbursts around close-range threats.
• AP-DS Anti-Armor Rounds: Designed to punch through heavily armored targets that survive initial interception layers.
• Configurable Ammo Loadouts: Kastiel-style programming enables the turret to select ammunition per threat type.

WEAKNESSES

• Power-Hungry: Ion field generator significantly increases power draw, potentially taxing a ship’s reactor under prolonged use.
• Limited Range: Not effective outside of inner defense envelope (sub-kilometer range). Must be paired with longer-range systems.
• Friendly Fire Risk: Baradium airburst or sabot rounds may be hazardous in close fleet formations or near civilian craft.
• Overpenetration Risk: Baradium or sabot rounds can cause catastrophic damage to internal hull sections or nearby allies in close formation.

DESCRIPTION
The Ironfang Close-In Interdiction System is the Commonwealth’s final word in kinetic-electronic point defense — a fusion of traditional rotary firepower with modern SIGINT-informed versatility. Mounted in hull-integrated or recessed rotating turrets, the Ironfang delivers high-velocity 20mm rounds through a twin-barrel hypervelocity system, acting as the last and most lethal barrier in the Commonwealth’s multi-layered defense doctrine.

What sets the Ironfang apart from legacy CIWS systems is its Ion Sheath Generator — a microfield emitter mounted around the barrel mouth, which ionizes each projectile as it exits. This turns even purely kinetic ammunition into a dual-purpose payload, capable of disrupting ray shielding and scrambling the guidance systems of advanced warheads or boarding drones.

Its advanced munitions suite includes the Kastiel AMV round family, offering smart-switch capabilities between armor-piercing sabot, ion/EMP disruption, and fragmentation modes. Meanwhile, the infamous “Confetti” baradium-tipped airburst shells flood space with molten shrapnel, electromagnetic static, and high-velocity debris, ideal for swarm mitigation and pod denial.

Designed to work in tandem with long-range systems like the Thunderbolt II CIWS and Ovmar II missile defense network, the Ironfang dominates the interior threat envelope — where speed, adaptability, and brutality are paramount. Its compact turret design and magnetic acceleration make it ideal for escort corvettes, tactical support ships like the Fortan V, and minor production flagships. While unsuited for long-range engagements, in its domain, it is simply unmatched.
