US Navy to Shoot Extended-Range Harpoon This Year

ARLINGTON, Va. — The extended-range (ER) Block II+ version of Boeing’s AGM-84 Harpoon anti-ship cruise missile will be fired in test shots this year, a Boeing official said.

The Block II+ER features an upgraded fuel system and a better warhead that enable it to achieve twice the range — at least 130 nautical miles — of a Block 1C version, the missile currently in the operational inventory. The upgrades fit inside the existing missile airframe, allowing the Navy to avoid the cost of more separation testing. The existing Block 1C missiles can be upgraded to the Block II+ER configuration.

Troy Rutherford, Boeing’s director of cruise missile systems, told Seapower Jan. 10 that the net-enabled Block II+ will be making its final Operational Test shots this year in preparation for deployment on the Navy’s F/A-18 and P-8A Increment III version of the Poseidon maritime patrol aircraft. Initial operational capability of the Block II+ is planned for mid-year.

As a net-enabled weapon with a jam-resistant Global Positioning System capability and capacity to receive target updates in real time via Link 16, the Block II+ can be tied into the Navy Integrated Fire Control-Counter Air architecture, Rutherford said, and give the Navy more distributed lethality, one of the surface fleet’s top priorities. The all-weather radar seeker has a sensitivity 10 times that of the Block 1C

Boeing expects to offer the Block II+ER as a solution to the Navy’s Over-the-Horizon (OTH) requirement for a cruise missile for the littoral combat ship and the follow-on frigate.

“We’re at a cost advantage,” Rutherford said, noting the fleet’s familiarity with the Harpoon and is launch system and the integration with platforms that already has occurred with the Harpoon program.

The Navy plans to order 340 OTH missiles of the winning design, with deliveries beginning two years after contract award. Rutherford noted that on the surface side, there is no requirement for a net-enabled missile, but the Harpoon Block II+ER will have it anyway.

Rutherford said there is a lot of interest in the extended-range capability from foreign nations that already deploy the Harpoon.

Harpoon Block II+ ER increases the ship-launched Harpoon missile's range from the Block IC's (AGM/RGM/UGM-84D) and Block II's (AGM/RGM/UGM-84L) 70 nmi (81 mi; 130 km) to 134 nmi (154 mi; 248 km), along with a new lighter but more lethal 300 lb (140 kg) warhead (down from 221kg) and a more fuel-efficient engine with electronic fuel controls.

Interestingly, the range extension is not as large as that which was achieved with the Harpoon Block ID (RGM/AGM-84F). This version featured a larger fuel tank and re-attack capability, but it was not produced in large numbers primarily because its intended mission (warfare with the Warsaw Pact countries of Eastern Europe) was considered to be unlikely following the events of 1991–92. BLock ID range is 150 nmi (173 mi, 278 km)
