Development version

The above-mentioned unexpected defection of Lieutenant Victor Belenki or disclosure by the experts from the U.S. Air Force all the intricacies of jiffy – 25P significantly reduced the initial values of battle . Over time, the Russians themselves have realized the obvious imperfections plane and have a bit early planning some design changes . Anyway, this situation even require the necessary modernization of the machine. Therefore, it developed a new variety of MiG- 25PD with completely modified avionics and an arsenal of combat , as well as newer, more efficient powertrains . Radar Smiercz -A was replaced already shown in the specification , newer type N -005 Sapfir -25 , which constitutes , in fact, used in the development of radar fighter M1G – 23ML ” Flogger ” . Was N- 005 pulse Doppler radar with visible and guidance in the lower hemisphere aircraft and increased to about 11o km detection range . Radar supplemented with a new system to detect and track infrared TP- 26Sz – l , which can automatically locate and identify targets 45 km away . modernized the missiles R- 40R and R- 40T , installing new homing heads in two versions: dog tags  guided and infrared . obtained in this manner almost double their range of detection. New versions designated R- and R- 40RD 40TD . to improve flexibility and increase combat capabilities using the outer pair of R -40 can be replaced by four samonaprowadzającymi infrared short-range missiles R-60/R-60M ( in NATO code AA- 8 ” Aphid ” ) . MiG- 25PD was also new turbojet R- 15BD -300 . The difference obtained was not great , the modifications to the gearbox, especially aggregates . Since 1979 , aware of the weaknesses of the earlier MiG – 25P , it was an effort to modernize the machines that were still in service in linear units . Usually, any improvements made on the occasion of the general survey . The modification resulted in the introduction of a slight extension of the front part of the fuselage , install the N -005 radar Saphir -25 and TP- 26Sz termonamiernika -1 and modernization of engines to the standard R- 15BD -300 .  modified aircraft MiG- 25PDS designation. As you may have already mentioned above, of course, on request of some countries in the Middle East has been developed based on the MiG – 25PD also seriously depleted export variant fighter. Despite the fact that the MiG -25 ” Foxbat was initially conceived as a fast interceptor , they realized that the performance of such aircraft in flight speed should also check the machine exploratory , perhaps even serving a closeup . A prototype version of an exploratory E – 155R made its first flight March 6, 1964 year, which is interesting in the six months before the actual prototype fighter variants . That is how the MiG- 25R and its derivatives. I think that this particular variant is interesting enough that it is worth quite a separate page, which read as soon as it appears , of course , hot urge all concerned. Certainly unusual and extraordinary performance of the MiG – 25PD and MiG- 25R encourage the Soviet air force commanders and air defense to invent him more and more new jobs and bringing new requirements. One of them was the idea of using ” dwódziestkipiątki ” to a ” silencing ” defense . Oprowadziło to the creation of a prototype E – 155K , and the aircraft MiG- 25BM shock . Mikoyan Bureau has taken the effort to design an improved version of the MiG -25M -powered R- 15B -300, which, however, quite niespodziewania caused a lot of problems as a result of which this time did not pass the state tests . Apart from this , to the emergence of the early 80’s a better solution – a new interceptor MiG -31 ” Foxhound “, undermining the sense of the MiG project -25M , which after all , and so far inferior to his future successor. Below is the brief description of most of the known development versions of this aircraft : MiG- 25PU – Two-seat training version of NATO marked as ” Foxbat – C”. Like most all varieties of combat aircraft that were designed directly for operational training flight crew , the MiG – 25PU was devoid of most of the weapons and combat systems , including a radar . MiG- 25R , RB, RBW – A variety of exploratory MiG – 25P . Wider material for the development of this structure umieszciłem in a separate subpage . MiG -25M – Designed as the best of the existing variants of combat ” Foxbat ” with a slightly improved tracking system objectives and improved powertrain . For the new MiG -25M provides two new turbojet R- 15B -300 . Small redesign of an existing engine variant R- 15BF2 -300 allowed to achieve the appropriate 9800 N without afterburner and 12,970 N with afterburner . Two MiG – 25P was converted to a trial , the first of which has already flown 30 August 1973 year. MiG -25M was undoubtedly an improvement over the older version. However, production of motor R- 15BF2 -300 made ​​a lot of trouble . Other subsequent versions of the MiG -25 proved to be much more economical in fuel consumption and the MiG -25M , in principle, have to remain only in the prototype . During the design and the first flight test was used temporarily if an E – 266m , when the first M1G -25M was used to in the regulation of a series of new records and climb to the specified time limit . Built originally as a MiG- 25RB aircraft , flown by test pilots to change Fedotov and Ostapienkę , established May 17, 1975 , three new records until the climb. From 22 July 1977 Fedotov use the same aircraft for the establishment of a new world altitude record , reaching 31 August 1977 , the amount of 37,650 meters . However, the MiG -25M , despite the establishment of these record results certainly never entered service . Its construction has created difficulties of a technical nature , so the plane did not pass state tests . In fact, as I mentioned earlier , to accede to work on the project more advanced airframe – substitutes the future MiG -31 ” Foxhound ” (which is all it was very zbliżonegy to the MiG -25M , but it was fully adapted to its innovative self at that time avionics ) , undermining the sense of entry into service of the new version slowly starzejęcego is technically combat aircraft , which, as it turned out, represented properly in spite of everything a little more fighting qualities compared to its predecessor . MiG- 25BM – As I wrote in the previous paragraph , of this variation was determined rather unusual job as a fighter plane the class. Namely, BM variant was adapted to tasks involving the neutralization of enemy air defenses . This version , called NATO ” Foxbat -F” , was intended for a specific task ” paving the way ” for reconnaissance MiG – 25R and other such machines in heavily defended areas. For this type of mission MiG- 25BM is equipped with a very sophisticated , comprehensive and integrated system for electronic countermeasure and track targets a Jaguar . It can detect , locate , select and prioritize risks and identify areas for missile launching his own and other cooperating aircraft . MiG- 25BM takes four shots przeciwradarowe CH- 58U with a mean range from 25 to as much as 300 km . Produced about 100 copies of these war machines , providing them Frontowemu Air Force Air Force ( Frontowaja Awiacija Wojennyjo – Wzdusznych Forces ) units already consuming older MiG – 25RB , thereby forming one squadron of each regiment designed to suppress air defenses . These machines entered active duty in linear units is likely in 1988.

    The new Zune browser is surprisingly good, but not as good as the iPod’s. It works well, but isn’t as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that’s not an issue, but if you’re planning to browse the web alot from your PMP then the iPod’s larger screen and better browser may be important.
