CHANGE: Navy To Begin Arming Subs With Ship-Killer Missile. “It’s a major shift after decades in which submarines focused on projecting power ashore, with their only anti-ship weapons being their rarely-used torpedoes.”

The effort to bring a modernized Harpoon back to the submarine fleet coincides with the delivery of the first Long Range Anti-Ship Missiles (LRASM) to operational Air Force units, a delivery announced Dec. 18. The precision-guided missile is designed to detect and destroy specific targets operating within groups of ships by identifying the target using links to drones or aircraft. An air-launched variant has been successfully tested aboard the Air Force’s B-1 bomber on a number of occasions, and it’s on schedule to achieve early operational capability on the Navy’s F/A-18 Super Hornet in 2019. Contractor Lockheed Martin has also test-fired LRASM from the same Vertical Launch System tubes used on Navy cruisers and destroyers.

Over the last handful of years, the Pentagon has made a concerted effort to get its ship-killing ability back, first under Obama’s last Defense Secretary Ash Carter and his deputy Bob Work — part of what they called the Third Offset Strategy — and under Defense Secretary Jim Mattis, whose focus on “lethality” picked up the offset effort under a new tagline.

Good.
