Indra disclosed the first dimensional specifications of its Squall cruise missile on September 30, 2026, at the ninth 2E+I Army 35 Forum in Toledo, Spain, alongside its Drizzle interceptor effector. According to the company, the 3.4-meter Squall carries a 60 kg warhead beyond 300 km, while Drizzle flies at more than 400 km/h and reaches 130 km with the help of a carrier drone.
Both weapons debuted on September 16 at the UNVEX unmanned systems fair in San Javier, Murcia, where Indra withheld Squall’s size, weight and warhead data. Toledo puts them in front of their intended customer. Indra pitches the pair as cheap, replaceable munitions that can be launched at scale to saturate enemy defenses and erode an adversary’s economic capacity, a cost-exchange logic the company ties to lessons from the war in Ukraine and from Spain’s role in the Eastern Flank Deterrence Initiative (EFDI). The forum also showcased three Special Modernization Programs (PEM) in which Indra is involved: SANTAM, ARACNE and COAAAS.
Squall Cruise Missile and Drizzle Effector: Range, Payload, Launch Modes
Indra describes Squall as the first cruise missile designed and built in Spain. It measures 3.4 meters, has a maximum take-off weight of 150 kg and carries a 60 kg warhead. That 40 percent warhead fraction favors lethality over fuel volume. Indra lists command-and-control nodes, air defense sites and high-value infrastructure in the enemy rear as target sets. The missile flies at low altitude to shrink radar detection windows and uses multiple navigation and guidance modes designed to resist jamming and spoofing. Launch options include ramps, containers and tactical vehicles ashore, plus naval platforms.
Indra has not disclosed propulsion, cruise speed, seeker type, unit cost or a test schedule, which limits any independent assessment of survivability against layered air defenses. For scale, publicly available specifications put the Taurus KEPD 350 already in Spanish Air and Space Force service at roughly 1,400 kg, with a warhead near 480 kg and a range above 500 km. Squall weighs about one-ninth as much and carries one-eighth the warhead: a volume weapon, not a hardened-target penetrator.
Drizzle is an 80 cm effector built to engage drones, light vehicles and antennas, with an organic range of 80 km. A larger, expendable carrier drone extends reach to 130 km by flying the first leg and releasing several interceptors for the terminal phase; the carrier itself carries an explosive warhead and can serve as a strike vector once emptied. Guidance relies on an Indra-developed search and detection system that processes electro-optical and infrared imagery onboard in real time, with a radar sensor planned for later versions. Drizzle can act as the hard-kill layer of a counter-drone system, launch independently from the ground, or arm drones and helicopters.
Tarsis, ARACNE and COAAAS: Indra’s Special Modernization Programs on Display
Under SANTAM, the medium-range unmanned aerial system program valued at €364 million ($420 million), Indra will deliver 49 systems totaling 147 Class I aircraft, each under 150 kg, to the Army, Navy and Air and Space Force between 2028 and 2030. The family pairs the runway-launched Tarsis-W, which can carry light weapons, with the Tarsis-VTOL; Indra quotes around 10 hours of endurance and more than 120 km of datalink range. The VTOL variant is slated to replace the ScanEagle in Spanish Navy service. Indra frames SANTAM as a sovereignty program, nationalizing navigation, autopilot, communications, synthetic aperture radar (SAR), electro-optics and propulsion across roughly a dozen Spanish suppliers.
ARACNE, developed with EM&E Group, combines SmartEar radio-frequency detection, the Brontes jammer, the Nemus AESA radar, an EM&E electro-optical sensor and an EM&E remote weapon station under a single command and control node that also fuses third-party sensor data. A €30.24 million contract covers 14 systems, seven fixed and seven mobile. Drizzle is designed to slot into exactly this kind of architecture as an extended-range hard-kill layer.
The Semiautomatic Anti-Aircraft Artillery Operations Center (COAAAS) is the largest of the three. Indra won a program worth roughly €2 billion in 2025 to field 19 new centers built around its AirDef C2 software, already used at Spanish Air and Space Force air defense centers, and its MTR family of AESA radars, led by the MTR-10 multifunction tactical radar. The MTR-10 operates in rotating or static configurations and moves from transit to operation in under five minutes from an ISO 20 container footprint.
Analysis: The Toledo lineup shows Indra assembling a nationally sourced kill chain for the Spanish Army, from Tarsis sensing through COAAAS command and control to Drizzle and Squall effects. The weak link is demand. Spain has no published requirement for a ground-launched cruise missile, and Indra has released no unit prices for either new weapon. Cost-exchange arguments only hold once production costs are verified. Until then, Squall and Drizzle remain company-led products in search of a program of record, competing for funding against committed priorities such as COAAAS and the VCR 8×8 Dragón.
Near-term milestones sit with the funded programs: continued ARACNE fielding, first SANTAM deliveries in 2028 and the progressive rollout of 19 COAAAS centers. For Squall and Drizzle, watch for live-fire trials, disclosed propulsion and seeker data, and any Ministry of Defense requirement. Indra will point to its record: it says it has more than doubled VCR 8×8 Dragón deliveries this year after 18 months leading TESS Defence, with the 100th vehicle handed over this week.
