Harpoon Block II+
Abstract
The Harpoon Block II+ (HII+) retrofit kit procurement provides the Department of Navy (DoN) with an enhanced tactically navigation and targeting selectivity capabilities over the legacy Harpoon Block IC (HIC) inventory. Harpoon Block II+ is a Network Enabled, Air-Launched, Anti-ship Cruise missile with the ability to receive in-flight targeting updates, improving target selectivity and the engagement of moving maritime targets. Additionally, the system utilizes the Global Positioning System to provide in-flight updates coupled with an active radar seeker for accurate targeting. The program procurement budget keeps pace with evolving enemy threats by providing a network enabled, anti-ship cruise missile capability, which compliments the attributes of associated launch platforms. The survivability of the HII+ is increased over the HIC due to the upgrade retrofit kit, increasing the lethality of the weapon system. The DoN's planned procurement modifies legacy HIC with the retrofit kits, to include procurement of Captive Air Training Missiles (CATMs), increasing the Anti-Surface Warfare capabilities of Fleet Forces. The Harpoon seeker upgrade program will modernize current seekers, designated 3700-3, to increase the targeting precision, reliability, and survivability. The program is the result of a successful Small Business Initiative, which will upgrade legacy 3700-7 to 3700-4+ seekers. The 3700-series seekers were designed to sequentially search, detect, acquire, and track a surface target in the designated Area of Uncertainty. The modified 3700-4+ seekers provide improvements in the sequential search radar probability of acquiring the intended target, and provide improved Electronic Protection which significantly increases the probability of engaging a valid surface target in a complex environment. These attributes of the 3700-4+ seekers will ultimately increase survivability and lethality of the Harpoon missile weapons system, and are intended to support the procurement of the Harpoon Block II+ missiles. The Encapsulated (ENCAP) Harpoon Block IC (HIC) missiles provides Navy Los Angeles-class nuclear attack submarines (SSN) a sub-launched, all-weather, long-range Anti-Surface Warfare (ASuW) missile to attack enemy warships at stand-off ranges, to include Surface and Amphibious Action Groups. The ENCAP Reconstitution Program will refurbish and recertify 60 existing ENCAP HIC all-up rounds from deep storage to an "as-new" war-ready material condition (ENCAP Harpoons were placed in deep storage in 1996). The controlled storage conditions achieved by the missile capsule have preserved the material condition of the weapon system, allowing for relatively quick recertification and reissue. Due the ease and speed of missile recertifications the ENCAP HIC Reconstitution Program will fill a critical, time sensitive ASuW capability gap and meet Speed to the Fleet requirements. This program is funded under OPERATIONAL SYSTEMS DEVELOPMENT because it includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate funding in the current or subsequent fiscal year.
