Air combat and stealth

Introduction

For a long time, visual detection was the only type of detection possible. But in World War II, two significant advances appeared: radar, as well as radar- and IR- -guided missiles. Until 1970s, these were defeated through jamming and decoys. Early German attempts at building LO aircraft – Ho-229 – never got anywhere, albeit their RAM paint utilization at snorkels and aircraft was noted. In United States, first attempt at reducing the radar signature of aircraft was on U-2, by utilizing RAM paint, but it was not very successful. First actual stealth aircraft appeared in early 1960s – SR-71 Blackbird, which utilized shaping such as canted surfaces to reduce radar signature. In 1970s a second generation of stealth aircraft appeared with B-1A, and also began a programme of development of VLO aircraft. Result of that was diamond-shaped F-117, to soon be followed by B-2. All these aircraft successfully performed against enemy air defenses, but in the case of B-1A and later aircraft, their performance against air defenses was similar or identical to performance of conventional aircraft they were deployed alongside. Fourth generation of stealth aircraft are F-22, F-35, PAK FA, J-20 and J-31. While still stealth aircraft, they sacrifice stealth characteristics for the sake of better flight characteristics, allowing them to match conventional fighters in terms of maneuverability. However, their stealth requirements make them larger and heavier than comparable conventional aircraft, thus sacrificing kinetic performance for the sake of stealth.^1 Read the rest of this entry »

The 90% Solution, Some Guy Called ‘Pareto’ and Why the Best Fighter Pilots are Often Seen as the Laziest

Leading Edge

getoutIt became apparent to me during my last tour that a lot of the effort that I put into my work was inefficient. I remember speaking to a senior officer whilst I was deployed to Kabul, Afghanistan with the US Army and she said – ‘you have to just get the work out of the door as complete as you can – aim for the 90% solution’.

In the military we have to be as efficient as possible because we work with taxpayer’s money and there is a lot of work to be done. The workload on some postings can be quite extreme and I have had tours that are no exception; I have worked genuine 12 to 16 hour days in my career for 5 days a week (or 7 days a week on ops, which, of course, is entirely to be expected). Now, I get that people in…
