The Republic of Korea Navy will use its new P-8A Poseidon maritime patrol plane to detect underwater North Korean threats.
The Republic of Korea Navy (ROKN) is now using operationally its new fleet of six P-8A Poseidon maritime patrol plane, after their arrival in in South Korea final yr. In accordance with Yonhap Information, officers stated the plane are “tasked with detecting underwater North Korean threats.”
The plane had been ordered in 2020 as a part of a International Navy Sale (FMS) and arrived on the Naval Air Command in Pohang in June 2024, in two batches of three plane every. The Poseidons will exchange 15 Lockheed P-3 Orions nonetheless in service, of which eight are within the P-3C-III+ normal and 7 within the extra superior P-3CK normal, based on FlightGlobal.
An eighth P-3CK was lately misplaced throughout a routine coaching flight on Might 29, 2025, inflicting the demise of the 4 crew members. An investigation is presently being carried out to find the causes of the crash, which reportedly occurred six minutes after takeoff and is the one of the kind in ROKN service because the introduction in 1995.
Following the supply of the brand new P-8s, the ROKN continued the coaching for each air and floor crews. After a yr of coaching and operational analysis, the plane “have been assessed match for operations” and able to “participate in anti-submarine, anti-surface ship and maritime patrol missions.”
North Korea’s underwater threats
The operational introduction of the P-8, though it was already deliberate to occur by mid-2025, comes at a fragile time with North Korea flexing its muscle tissues within the maritime area. Actually, North Korea’s naval forces are present process their most bold modernization in a long time, which could sign a shift from their previous use of the vessels.
In April 2025, state media showcased the Choe Hyon-class frigate, a brand new 5,000‑ton multipurpose warship which was outfitted for the primary time in North Korea with phased-array radars, vertical-launch missile techniques (VLS), cruise and surface-to-air missiles and a helicopter deck. A month later, the second ship of the category, the Kang Kon, capsized throughout launch however has been rapidly salvaged, with plans for extra vessels.
Concurrently, North Korea can also be accelerating on the event of latest submarine capabilities. For an occasion, the nation unveiled the development of what’s stated to be a nuclear‑powered submarine (est. 6,000–7,000 tons) which might doubtlessly carry about 10 ballistic missiles.
The brand new frigates and submarines would possibly have the ability to prolong North Korea’s attain, enabling missile strikes on land and sea targets. The actual capabilities of those vessels are unclear, nevertheless they aren’t to be ignored to keep away from miscalculation and scale back the dangers.
P-8 Poseidon
The P-8A Poseidon is a long-range, multi-mission maritime patrol plane developed by Boeing for the U.S. Navy to switch the growing older P-3C Orion. Primarily based on the 737-800ERX airframe, the plane incorporates quite a few structural and techniques modifications to fulfill the demanding necessities of anti-submarine warfare (ASW), anti-surface warfare (ASuW), intelligence, surveillance and reconnaissance (ISR), and search and rescue (SAR) operations.
Internally, the Poseidon is provided with a sophisticated mission suite that integrates multi-mode radar, an electro-optical/infrared (EO/IR) turret, magnetic anomaly detector (MAD), and a complete acoustic system able to processing knowledge from over 100 sonobuoys. The plane can also be able to deploying Mk 54 light-weight torpedoes, depth costs, and AGM-84 Harpoon anti-ship missiles from each its inside bomb bay and underwing hardpoints.
The P-8A is presently present process a big functionality enhancement with the Increment 3 Block 2 (I3B2) improve. First flown in June 2025, the Block 2 configuration introduces improved multi-static acoustic processing, new mission techniques, an upgraded EW suite, and the mixing of superior weapons such because the AGM-158C Lengthy Vary Anti-Ship Missile (LRASM). The replace additionally consists of provisions for extra ISR and digital help payloads, rising mission flexibility.
Among the many key enhancements is the Excessive Altitude Anti-Submarine Warfare Functionality (HAAWC), which permits the Poseidon to launch torpedoes from excessive altitude utilizing a winged glide equipment. This improvement considerably will increase survivability by permitting the plane to stay outdoors the risk envelope of submarine-launched or ship-based air defenses.
To enhance survivability in contested environments, the U.S. Navy has additionally contracted BAE Techniques to develop the Superior Survivability Pod (ASP). The pod integrates radio-frequency and infrared risk detection, countermeasures, and a fiber-optic towed decoy system, offering safety towards radar-guided and heat-seeking missiles.
In service with the U.S. Navy since 2013, the P-8A Poseidon is now additionally operated by a number of allied nations together with Australia, the UK, Norway, India, and Germany. As maritime competitors intensifies globally, the P-8A’s multi-mission capabilities, ongoing upgrades, and interoperability make it a cornerstone of contemporary naval operations.
