Americas Lockheed Martin won a $46.4 million deal for the digital expanded ultra-high frequency multiple input multiple output optimized radar. This contract provides for the development of advanced radar technology solutions applicable to both next generation platforms and current generation platforms (such as the E-2D). To support a rapid pace of development, the contractor will […]View the full article

Some good points. In hc the main restriction is that when looking generically at asw you need to be able to loiter\hover at low alt at periodic places in order to drop bouys, lower sonar etc. I haven't tested mad but i seem to think mad will work (when fitted) at medium alt, but this could easy be wrong (and perhaps should be?) My asw patrols are based on a two ring octogon (or maybe hexagon, i forget) and at each node the unit loiters\hovers for 30 or 60 secs {probably it should be longer) so as to drop sensors. In between these it flies at low alt but I'm thinkng of having it fly medium alt for better electonic visual surveillance  

Americas BAE Systems Technology won a $67 million deal to exercise fiscal 2024 options to provide support services for the US Trident II D5 Strategic Weapon Systems program, the Attack Weapon System program, and the Nuclear Weapon Security program. This contract award also benefits a foreign military sale to the United Kingdom. Work will be […]View the full article

One of the limiting factors would be how far the Sonobuoy can transmit data to the processing equipment on the aircraft. To process data from a sonobuoy field the AC would have to fly at an altitude to receive data from all the buoy's. An article I just came across says that a Sonobuoy from as high as 30,000 feet. https://dosits.org/galleries/technology-gallery/locating-objects-by-listening-to-their-sounds/difar/ Here is another article on Sonobuoy's: https://www.militaryaerospace.com/sensors/article/14283490/antisubmarine-warfare-asw-sonobuoys-underwater-sounds Here is an article on how the whole process for detecting a sub works: https://nps.edu/web/slamr/-/disrupting-anti-submarine-warfare-with-autonomous-systems The lower the AC is to the water the easier it is for the sub to hear the aircraft. Once a contact has been acquired and the general location of the contact is known only then the aircraft drops down to a lower altitude to get a precise location of the contact wit MAD. I haven't been able to find out the transmission range to the aircraft of the buoy. That information may not be published for a good reason. To detect a surface ship you would first look for any electronic emissions. The electronic emissions will be detected long before the ship will be able to detect the aircraft. Since the noise a surface ship makes is trapped above the thermal layer of the ocean it can travel long distances. The only way to try an localize a surface contact is to use Time motion analysis. A good example for TMA was used in the Hunt for Red October by Sonar Technician Jonsey when he plotted the course of the weird sound. He was able to figure out what the course was of the Red October. The one unknown factor is what can Harpoon do and can't do. That is the question for TE to try and answer.

Americas An F-35B fighter assigned to US Marine Fighter Attack Training Squadron 501 (VMFAT-501) has crashed north of North Charleston. The mishap aircraft was part of a two-ship flight that took off from MCAS Beaufort. The second F-35B landed safely at Joint Base Charleston. Officials are now trying to find the F-35B that went down […]View the full article
