The U.S. Defense Advanced Research Projects Agency (DARPA), through the U.S. Air Force Research Laboratory, has awarded BAE Systems a $13.1 million contract to demonstrate a new, cost-effective optical seeker for precision-guided munitions. The seeker is designed to improve navigation, as well as automate target location and homing, for different types of munitions that are used in GPS-denied and other contested environments.

BAE Systems tested the seeker during the first phase of DARPA’s Seeker Cost Transformation (SECTR) program. The SECTR seeker integrates with a wide range of weapon platforms that use munitions and can operate in day or night. It enables autonomous precision guidance via passive electro-optical and infrared sensors in environments where GPS navigation is unavailable or unreliable.

This phase of the program will conclude in July 2019 with multiple test firings on several precision-guided munition platforms.

Los mas sofisticados, como el Excalibur, tienen una precisión de 6 mt., pero entonces si que estamos hablando de altisimos costos de adquisición.

Con respecto a Holanda, adquirió el M1156 que tiene la misma precisión que el israelí.

No se de donde sale éso de los 50 mt. de CEP.

USN reveals concept to defend aircraft against missile attack with interceptors
08 May, 2018

A US Navy document reveals a new concept to protect large cargo and surveillance aircraft from incoming missiles using small interceptors launched by the targeted aircraft themselves or by unmanned escort aircraft flying next to them... the US Naval Air Systems Command (NAVAIR) is evaluating a concept called Hard Kill Self-Protection Countermeasure System (HKSPCS)... The HKSPCS would attempt to shoot down incoming missiles by firing salvos of interceptors at them. The interceptors could be launched either internally or from within a pod attached manned aircraft. Alternatively, a new class of unmanned escort aircraft could fly alongside the manned transports and surveillance aircraft and fire interceptors at incoming missiles, NAVAIR’s document states.
...
The HKSPCS concept for large military aircraft also comes two years after the US Air Force began working on a similar concept. In January 2016, the USAF awarded Raytheon a contract worth up $14 million to research and develop new missiles, including a miniature self-defence munition (MSDM). The USAF also has been developing a concept called “loyal wingman”, which involves digitally tethering a manned fighter to one or multiple unmanned aircraft that can provide complementary roles, including self-defence.

NAVAIR describes two “notional” options for a HKSPCS system in the RFI. The first option calls for an internally mounted system with a total weight not exceeding about 1,040kg (2,300lb). The second option would be a pod mounted system weighing from 385-1,313kg and sized to kill four to 10 incoming missiles, factoring in the interceptor’s calculated probability of kill.
Responses to the RFI are due by 21 May,

Cualquier sistema SAM de muy largo alcance que sea adquirido por un país causa inevitablemente malestar en sus vecinos, en especial los de muy alta performance como el THAAD o el S-400.

Recordemos el frenesí diplomático de Rusia cuando se hablaba de desplegar el THAAD en Europa Oriental, o las protestas histéricas de China y Norcorea
