L3Harris Advances MK-48 Torpedo Tech with New Fiber-Optic Cable for U.S. Navy

-
Image
L3Harris Technologies has successfully passed a critical milestone in the development of its advanced fiber-optic torpedo cable system, known as the Improved Post-Launch Communications System (IPLCS). This achievement, marked by the completion of the Proof of Design (POD) phase, signals a significant leap forward in undersea warfare capabilities for allied naval forces. The IPLCS is now poised to enter full-scale production, ready to be deployed by both the United States Navy and the Royal Australian Navy. Photo: l3harris.com The IPLCS represents a transformative upgrade over legacy copper wire systems traditionally used to guide torpedoes. By replacing outdated copper cables with ultra-thin fiber-optic lines—comparable in thickness to a 20-pound fishing line—L3Harris has introduced a solution that is exponentially more capable. Despite its slender profile, the fiber-optic cable offers thousands of times more bandwidth, vastly improved reliability, and extended communication range. Th...

AIM-260 Enters Production: Could This U.S. Missile Outclass China’s PL-15

-
Image
The AIM-260 Joint Advanced Tactical Missile (JATM) is poised to enter production, marking a new chapter in the evolution of air-to-air warfare. After years of secrecy and speculation, the U.S. Department of Defense has publicly requested funding for the procurement of the AIM-260A in its Fiscal Year 2026 budget—a move that signals the missile’s transition from development to operational readiness. A Missile Born of Strategic Necessity The AIM-260 program began in 2017, driven by the need to counter emerging threats, particularly China’s PL-15 long-range air-to-air missile. The PL-15, equipped with a dual-pulse rocket motor and advanced guidance systems, posed a serious challenge to U.S. air dominance. In response, the U.S. Air Force and Navy initiated the JATM program to develop a missile that could not only match but exceed the capabilities of the AIM-120 AMRAAM, the current workhorse of American air-to-air engagements. Budget Breakdown and Production Plans For the first time, the U.S...

The Danish Ministry of Defence has confirmed that its interim solution for short and medium-range air defence will now be converted into a permanent capability, marking a significant step in strengthening the nation’s integrated air defence architecture. The acquisition includes two NASAMS batteries from Kongsberg, two IRIS-T SLM systems from Diehl, and two VL MICA systems from MBDA, ensuring a layered and versatile shield against aerial threats. In addition, Denmark will procure two long-range SAMP/T systems from MBDA, further enhancing its ability to counter high-end threats and contribute to NATO’s collective defence posture. NASAMS.
