The IC-121 Caracara Class is a ship tasked entirely with the mission of air-defense. It was classified as an "air-defense destroyer" or "ADG", while still excluding the vessel class from the Inyurstan Navy's official count of destroyers.

Sensors

A tandem radar suite is the backbone of the Caracara's air-defense capability.

Block I: For long-range, high-altitude targets, the V-43SM ultra-high frequency (UHF) radar is used, mounted closer to the deck of the ship. Medium distances and fire-control for the ADM-140 Liberator are controlled by the similar V-40s1 radar and its additional counterpart, the DV-10-S. The V-43 boasts a longer range than its cousin, the V-40 series, but at the cost of accuracy and resolution.
Block II: An upgraded V-43SMv2A is the main long-range radar of the Caracara Block II models. In initial models this worked largely as an "early warning" radar, but thanks to the addition of high digital computing power via space/time adaptive processing in the v2A/Block II upgrade, the V-43SMv2A gained significant target tracking and fire-control capabilities of targets out to 400km. For medium to short range and low-altitude targets, the earlier adaptations of land-based radars have been replaced with the new-build, high-mast ESQ-G57-2 "Flashpack" dual-scanner radar, which serves as the primary targeting radar for a wide variety of targets, including fighters, drones and sea-skimming missiles. The Flashpack consists of 2 back-to-back multiband radar rotating while scanning, allowing for intense resolution and accurate fire control. By saving space and processing power with a singular radar for the medium range intercepts, the Block II modules are able to mount additional weapons systems and short-range sensors elsewhere. According to Navayelle Systems, Inc, the Flashpack boasts a 33-50km detection envelope against sea-skimming missiles.

The SIREN short-range infrared tracking, targeting & awareness suite is also added with the Block II+ designs, allowing the ship to track and engage targets within visual range in environments with high clutter and/or high-jamming.
Block III: It is estimated that power source & cooling improvements to the "Flashpack" radar increases the number of targets tracked to over 600 simultaneously tracked and over 100 engaged in a single salvo. Defense experts also surmise that the range against sea skimming missiles has been increased to 45-80km due to the higher positioning of the radar mast.

Armament

See: Variants
The main feature of this vessel is its frontal 8x4-cell and rear 2x4 SSU-10 (Mk-41-compatible) VLS (32 cells total), a system which contains all of its primary anti-air weaponry. 48 RIM-162 ESSM (Inyurstan reporting name: ADM-162 Fanatic) missiles are quad-packed into twelve VLS cells and used as the go-to ordinance for within visual range engagements. 20 indigenous ADM-40b Sea Liberator missiles are loaded singularly into cells and are ideal for long-range (out to 350km) and medium range (over 24km) engagements of enemy fighters, drones and incoming missiles. ADM-140b missiles can also be adjusted and guided with help from an AEW or AWACS aircraft to help eliminate effects of the horizon line. An additional pair of arm-launched (one forward, one aft) C-40M Caçador missiles give the ship redundancy coverage in both medium and within visual range interceptions.

From Block II onwards, a number of VLS cells were fitted with SyCMAT ABM missiles for integration in maritime missile shields and defense against anti-ship ballistic missiles.

Caracara class destroyers also mount x3 ADM-113 Corsair missile CIWS; two are side-mounted with partial, though overlapping, coverage of the aft, while another is front-tower mounted, providing a 240° window of coverage. Combined, the coverage of the three batteries amounts to at least 360°, with areas of overlap. A key feature of the Corsair CIWS is that it can independently target incoming missiles without draining processing power from other shipborne radars, allowing the main fire control systems to engage other targets at or near maximum quantity. Further, using IR-targeting, the Corsair can also operate without emitting. Unlike VLS cell-based short-range and CIWS, the Corsair system can be manually reloaded by the crew.

As a last resort against missiles and drones, the Caracara mounts two RK-35 Disruptor CIWS. The Disruptor is comprised of a three-barrel rotary cannon and fires a x35mm round. Ammunition can be set to airburst to increase hit liklihood or kinetic shells to ensure destruction of a target; though in operation usually both ammunition types are loaded.

Counter-Measures

The main ECM system of the Caracara class is the American-made SLQ-32A(V)4 Countermeasures suit, used for active deception and angle jamming of enemy warheads. This system also integrates with the MK36 SRBOC decoy mortar which fires infrared flares and radar chafe into the air to help obscure the ship's signature. It also mounts the E-7 Decoy Launcher, which ejects a dummy missile emitting active signals to seduce incoming anti-ship missiles away from the vessel. The SHATSI (Soft & Hardkill Anti-Torpedo System Integration) Counter-Measure suit works with the SEA SENTOR passive array to detect incoming torpedoes and neutralize the incoming target with a combination of softkill (including 12 expendable decoys) and hardkill (including lightweight anti-torpedo munitions) systems.

Service

The Caracara class has seen service with the Inyurstan Navy worldwide. They were heavily involved in ship-to-ship combat in various stages of the Lolloh-Ruolnik War, and both ships sunk were done so in this conflict. However they proved effective at engaging and destroying sea-skimming missiles outside of visual when paired with the navy's E-2D Hawkeye AEWC aircraft, saving carrier groups from Lollohian AShM's on several occasions. Several Lollohian Yaeger Fighters were also engaged and destroyed.

Variants

Block I: Original commission model using primarily "ported" land-based radars.
Block I-E: Legacy upgrade model with V-43SMv2A implemented.
Block II: Major systems improvement capacity. Includes integration with the SyCMAT Anti-Ballistic Missile.
Block II-CU: "Anti-UAV" enhancements added, including removal of the arm-launcher C-40, and replacement with a pair of RK-23 rotary cannons and additional EW measures. Torpedo tubes also removed and replaced with hard-kill measures against both torpedoes and maritime UAVs.
Block III: In-development build, featuring lowered RCS surfaces and quieter propulsions systems. Removal of the arm-launcher C-40 and [X MANY] VLS cells, in exchange for anti-UAV measures and increased sensor output.
