The Penguin anti?ship missile from Kongsberg Gruppen ASA - a classic seeker still in front-line use

The Penguin anti?ship missile has quietly become a classic, pairing active radar guidance with low?level sea?skimming profiles on NATO helicopters and fast patrol craft. This classic keeps Kongsberg shares on the radar of defense?focused investors (ISIN NO0003043309).

Penguin anti?ship missile is not a shiny new prototype, but a low, grey presence slung under helicopter pylons, its sharp nose jutting out like a spear over choppy water. Crews talk about how it just sits there, quiet and self?assured, until the launch call comes.

How Penguin came to sea

Penguin anti?ship missile from Kongsberg Gruppen ASA traces its roots back to the Norwegian Navy’s need for compact ship?killing power in the 1970s. Norway’s coast is long and jagged, with fjords that demand agile weapons rather than giant blue?water missiles.

Engineers at Kongsberg worked with the Norwegian Defence Research Establishment to craft a missile light enough for fast attack craft, yet smart enough to hit a moving target on a rough sea. One of those engineers, former project lead Øyvind Tørum, later described Penguin as “a weapon built for weather, not for show”.

What the seeker can do

Painfully aware of cold spray and low clouds, Penguin’s designers gave it an autonomous imaging infrared seeker that can pick out a ship’s heat signature against the sea. That allows the missile to fly a sea?skimming path and then climb for a final dive onto the target’s vulnerable sections.

The weapon is relatively compact, roughly 3 meters long with a launch weight under 400 kilograms, so helicopters like the SH?60 Seahawk can carry multiple missiles without feeling sluggish. In practice, pilots say they notice the extra weight on take?off, but once in cruise it feels like part of the aircraft.

Variants and export story

Over time, Penguin evolved through several marks, from early ship?launched versions to air?launched variants carried by helicopters and maritime patrol aircraft. The missile found export customers in NATO, including the United States and Turkey, expanding Kongsberg’s reach beyond Scandinavia.

An official US Navy fact sheet notes that the AGM?119 Penguin delivers a high?explosive warhead with programmable impact modes, giving operators a choice between detonating on contact or after penetrating the hull. That flexibility matters when you might face everything from patrol boats to larger surface combatants.

Using Penguin day to day

For crews, Penguin means drills on cold decks and noisy flight lines rather than showroom floors. A Seahawk pilot from a NATO exercise once described leaning out during loading, seeing the missile’s fins just a forearm’s length away, coated with fine salt mist from the last sortie.

Integrating the missile into daily operations requires software alignment with the aircraft’s fire?control systems and regular seeker calibration. Kongsberg’s documentation emphasizes maintaining the missile’s environmental tolerances, particularly for storage on exposed decks in Arctic and North Atlantic conditions.

How Penguin fits Kongsberg today

While newer systems like the Naval Strike Missile grab headlines, Kongsberg still lists Penguin as part of its missile portfolio for legacy platforms. The company positions it as a proven option where full retrofits to newer missiles would be costly or constrained by space.

CEO Geir Håøy has repeatedly stressed that sustaining long?serving products like Penguin underpins Kongsberg’s reputation with defense customers, who value continuity alongside innovation. For risk?aware investors, that mix of old and new systems is part of Kongsberg’s appeal.

Stock and listing context

Overall, Penguin remains a classic, quietly contributing to Kongsberg’s defense revenues alongside more modern missiles. Kongsberg shares (ISIN NO0003043309) trade on the Oslo Stock Exchange in Norwegian kroner, reflecting the group’s position as a major Nordic defense and technology supplier.
