Following a series of drone overflights directed against Danish targets in September, the Danish Ministry of Defense has concluded an order with Kongsberg for coastal defense missiles.

After a clear provocation succeeded in closing down Copenhagen Airport on the night of September 22, Danish authorities identified four Russian-linked ships that potentially could have been used as launch platforms:  the Russian-flagged coastal freighter Astrol 1 (IMO 9906544), the dark fleet tanker Pushpa (also known as Boracay, IMO 9332810) and the coastal freighter Oslo Carrier 3 (IMO 9366146). The Astrol 1 had a particularly suspicious track relative to the drone flights detected.

The Danish Ministry of Defense’s Material and Procurement Agency (FMI) did not specify the quantity of coastal batteries procured, but noted that the contract was awarded on a single-bid basis in recognition of the urgent operational requirement. Such a decision will have been easy to make, as in March the Danish Navy also ordered the same Naval Strike Missile for its Iver Huitfeldt-class frigates. Reflecting the rapid procurement process, the coastal batteries will be in operational service in 2026.

The Danish press statement tied the procurement specifically - but not exclusively - to the defense of the Danish Straits and the Western Baltic. Being mobile, the system could also be rapidly deployed to Denmark’s western coast, or even to Greenland should there be a threat of an incursion in that area.

Denmark has also been concerned about the numbers of dark fleet tankers coming from the Russian oil terminals at Primorsk and Ust-Luga, heading through the Baltic and then the Danish Straits. Many of these appear to be uninsured, falsely-flagged, and noncompliant with safety standards.

Russia has a particular interest in bullying Denmark - not a recommended practice since Viking days - for its stalwart support of Ukraine. In particular, Denmark is supporting Fire Point’s development of the Ukrainian FP-5 Flamingo ground-launched cruise missile, which is believed to have a range of nearly 2000 miles.
