Word “stealth” has lately become a catchword used to define the weapon – mostly aircraft – as “superior”, with little or no thought as to what the term actually means. Stealth fighters, stealth bombers, stealth ships… even stealth tanks, the craze is in full swing. But how much do these weapons deserve the label? What is stealth? Is merely having low radar cross section enough – as commonly held – to define the weapon as “stealth”? Is USAF stuck on denial that no military advantage lasts forever, or even on denial that it never understood the true meaning of stealth? Every successful use of stealth aircraft had seen them acting as a support of, and being supported by, an array of nonstealthy aircraft – AWACS, standoff jammers etc. Yet USAF is now aiming for an all-stealth tactical fighter force, even though it will make the force less flexible and arguably less capable as well. How stealthy these aircraft really are, and what are their vulnerabilities? Read the rest of this entry »

F-35 is the newest Western flying piano. Apparently US have already forgotten all the lessons of World War II and Vietnam war, where such impressive-on-paper-but-sluggish fighters ended up on mercy of far more nimble fighters and were thus relegated to ground attack roles. In fact, F-35 was designed as a ground attack aircraft, only to be pressed into service as “multirole” fighter after F-22 killed itself with cost overruns (how decision-makers figured that three-service aircraft would be better than a single-role single-service aircraft in that respect is beyond me, especialy after Aardvark disaster; only thing F-35 has for it is that it is lighter than the F-22, allowing for limited cost savings for some variants when compared to the F-22). And despite what some might think, F-16 was the first – and last – US fighter designed with maneuverability in mind; both P-51 and F-86 ended up maneuverable by pure luck, as they had to have low wing loading to function as high altitude bomber interceptors, and P-51 also got equipped with excellent British Merlin engine. F-22 is similarly a high-altitude bomber interceptor, and while it does have good maneuverability, it is not designed for it, as evidenced by the fact that it needs thrust vectoring to achieve angle of attack required for maximum lift; comparably low wing loading (about same as F-15C) and high thrust-to-weight ratios are features required by its role as a high-altitude fighter.
Due to this maneuverability shortcoming, F-35 has to rely on surprise attacks against the enemy: detect before being detected. That is, after all, entire purpose of stealth. But how stealthy is the F-35? Is it stealthy at all? What must be kept in mind is that stealth is not limited to just radar. For this reason, I will take a look at F-35s stealth in multiple areas.
