WASHINGTON — For the first time, a littoral combat ship (LCS) has successfully launched a Harpoon surface-to-surface missile — but the missile failed to hit its target.
The LCS Coronado launched a Harpoon Block IC missile from a canister installed on its forward deck late Tuesday afternoon during Rim of the Pacific (RIMPAC) exercises near Hawaii. The target, the decommissioned frigate Crommelin, was about 20 nautical miles away.
"The missile left the ship as planned in the engagement plan," Cmdr. Scott Larson, commanding officer of the Coronado, said Wednesday during a phone interview while still at sea. "We saw visually a booster separation, and it looked as though the missile was on the correct bearing. We lost radar track as the missile moved down range."
"The data is still being analyzed to determine what the missile profile looked like," Larson added. "Indications are it was a negative impact. But it was successful in validating our ability to deploy that missile off the ship and not damage the ship."
The Naval Surface Warfare Center Corona Division, an independent analysis and assessment center, is reconstructing the firing and making a more definitive assessment of what happened during the missile shoot, Larson added.
It was not the first time an anti-ship missile was fired from Coronado, which in September 2014 conducted a feasibility launch of a Kongsberg Naval Strike Missile (NSM). But that test was from a box launcher simply set on the edge of the flight deck, and the test was not part of a larger exercise.
The Navy is working to give its LCSs and subsequent frigate variants a bigger punch, and the installation of a surface-to-surface missile is a major feature of the upgrades. Both the NSM and the Boeing-built Harpoon will be installed on deployed LCSs, the first of which is the Coronado. The LCS Freedom will be fitted with the NSM by the time it deploys this winter to the Western Pacific.
The Harpoon installation on Coronado is still incomplete. The ship arrived at Pearl Harbor June 29 for the RIMPAC exercises with Harpoon missile cradles for four missile canisters installed forward, but no canisters to carry the weapons. She left Pearl July 12 with one canister installed and loaded with the missile used July 19.
The missile, Larson said, was "partially detanked" without a full fuel load "due to range safety directives" from the Pacific Missile Range Facility.
"We loaded one missile for the test, loaded on the port aft launcher, known as Cell No. 4," Larson said. "It was a structural test firing, we wanted to put it closer to the deck structure to provide a more meaningful analysis."
The missile is not yet integrated with Coronado’s combat system, Larson said, but data from the system was used by the Harpoon engagement planner to carry out the launch.
"Harpoon in the present installation is a stand-alone weapon system," he said, but future systems will be fully integrated.
It’s the second RIMPAC for Coronado, which also attended the world’s largest naval exercise in 2014. It’s been a busy time.
Other exercises, he said, included anti-fast attack craft scenarios, "small boat operations, special operations to support elements boarding illicit traffickers, using LCS as a staging base. Also humanitarian assistance/disaster relief exercises using Coronado as a base. And a lot of search and rescue exercises using the embarked MH-60S helicopter."
Coronado is also carrying an MQ-8B Fire Scout unmanned helicopter.
The drone helo hasn’t yet been flown in the exercises, Larson said, "but we’ll be flying quite a bit in the next several days."
Missions, he said, will include "mostly intelligence collection, surveillance, building a recognized maritime picture. We’ll classify and identify contacts of interest, perform over-the-horizon sensing, target reporting.
"We’re still in many ways developing the art of the possible for the MQ-8B," he added.
Larson noted that the aircraft, unlike most Fire Scouts deployed in years past, is fitted with a radar package.
"It has an inverse synthetic aperture radar, a core radar and a FLIR [forward-looking infrared] pod able to transmit real time video back to the ship," Larson said. "It can be a tremendous asset."
Coronado will return to Pearl Harbor after RIMPAC for a three-week continuous maintenance availability before heading west to begin a deployment operating from Singapore. When the ship leaves Pearl, Larson said, all four missile canisters will be installed and loaded with Harpoons.
The addition of the missile, he emphasized, is a huge boost for LCS.
"It’s very significant," he said. "It’s a huge win for the program, a game-changing capability for the LCS variant, for the Navy and the message we’re trying to send in Seventh Fleet."
And while the LCS-launched Harpoon went awry, the target ship Crommelin did not survive multiple strikes by other ships, sinking during the evening of July 19.
