Naval News – Lockheed Martin rapidly developed its new Lamprey multi-mission autonomous undersea vehicle: The company took just 14 months to develop Lamprey, with future plans to field larger variants and another drone by the end of the year. 

The War Zone – Lamprey can launch aerial drones, launch decoys, and fire torpedoes after arriving discreetly in an operating area by hitching a ride.

Defense News – Governments and militaries in Southeast Asia are turning to autonomous underwater tech to monitor subsea cables after a series of damaged infrastructure in the Baltic Sea, and recently, in sea lanes surrounding Taiwan.

Naval News – Seafaring nations face unique challenges in ensuring the safety, security and sovereignty of their nautical frontiers. Even in times of tranquility they must guard against threats such as terrorism, smuggling, illegal fishing, natural resources theft, and uncontrolled mass immigration. And when conflict does arise, these nations must have anti-submarine and anti-surface vessel warfare capabilities to defend against naval incursion or attack. Even before the outbreak of open hostilities, it is imperative that they be able to detect and track hostile naval forces engaged in intelligence gathering and other covert activities.

Clio’s Musings – A propulsion disabler (PD) is a small, passive, torpedo-like device that serves as a cheap, non-lethal mine and torpedo warhead. The proposed munition’s purpose is to destroy a ship’s external propulsion or direction-control mechanisms, leaving the vessel stationary. Production of PDs is possible with today’s emerging robotics technologies.Future PD devices could be used in an autonomous swarm that combines the smallest explosive charge with the greatest disabling effect by attacking a ship at its most vulnerable point. Once PDs become widely available, they may well be the weapon of choice by all navies against civilian ships. Similarly, disabling an enemy’s naval ship rather than sinking it will almost always be the superior choice, certainly for the U.S. Navy. The logic that makes this so will compel adversary navies to make the same choice.
