Ragnarok ::I zašto je F-15C bolji od F-16C?
Malo bolji radar ali avaks je tu za obojicu. A naoružanje im je isto tako da ne vidim šta je tu F-15 bolji kad je 16tica mnogo agilnija. Naročino za blisku borbu. To su simulacije u koloradu i pokazale
Tacno je da nose iste rakete ali koliko raketa nosi F-16 a koliko F-15 i kako se ponasaju kada nose veci broj raketa?
F-15 standardna konfiguracija:
Bez dodatnog rezervoara postize 1.7maha a bez raketa na nosacima postize maksimalnu brzinu.

Kako ? Sto ne prave nove...
Oni nisu normalni...
Treba odati priznanje na resursu aviona, kako ga produzavaju, kako ih odrzavaju i koliko lete. Naravno i ulaze se.
Evo i od Trimble-a o produzenju zivota F-15.
Citat:A Boeing F-15C is rated for a 9,000h service life. An F-15E was designed with an 8,000h rating, which the USAF has already extended to 12,000h. Both types are supposed to be retired from USAF service by around 2030.
Don't bet on it.
With production of the Lockheed Martin F-22 capped at 187 fighters, and F-35 deliveries delayed and slowed, the US Air Force is investigating how much longer it can preserve the fleet of 414 F-15C/Ds fighters and F-15Es fighter-bombers.
The goals are to double the lifetime of the F-15C to 18,000h and quadruple the service life of the F-15E to 32,000h, Boeing told Flightglobal yesterday. At the 32,000h rating, the F-15E would essentially be in perpetual operational service -- the Boeing B-52H of its era.
An F-15C has already entered a four-year cycle of fatigue testing, with an F-15E soon to follow. It was only four years ago that an F-15C disintegrated in flight due to a poorly manufactured longeron. The fatigue tests will discover if the airframe has any other hidden weaknesses that need to be fixed.
If the F-15 fleet is to serve for decades to come, its aging analogue systems will also need a refresh. The US Air Force has already funded a new digital core processor and an active electronically scanned array (AESA) radar. Now, the USAF is looking to upgrade the self-defence systems with an digital suite. The Eagle passive/active weapon survivability system (EPAWSS) could be launched in 2013.

A opet se kaze kako USAF nije zainteresovan za Silent Eagle.

Ma Ameri su izuzetno bogati, ali su duzni 15 hiljada milijardi dolara.
A džabe ti da stavljas stakleni kokpit u nase Orlove kad za njih nemas ni postene gume, creva i ostale gumene delove.

Citat:Boeing Receives $20 Million Contract to Upgrade F-15C Trainers
ST. LOUIS, Nov. 29, 2011 — The Boeing Company [NYSE: BA] received a $20 million contract in September from the U.S. Air Force to upgrade the visual systems in the F-15C Mission Training Centers. Twelve MTCs, located at Langley Air Force Base, Va., Royal Air Force Lakenheath, United Kingdom, and Kadena Air Base, Japan, will be upgraded with Boeing’s Constant Resolution Visual System (CRVS).
CRVS is the centerpiece of a complete training suite that provides 360 degrees of immersive training, with a significantly lower cost than previous visual systems. By using standard, off-the-shelf projectors, the system is able to take advantage of the rapidly improving technology emerging in the commercial marketplace.
“A key feature of the CRVS is the ability to train with the Joint Helmet Mounted Cueing System and night vision goggles, both of which will be used in the F-15C MTC,” said Mark McGraw, Boeing vice president for Training Systems & Services.
The Boeing CRVS reduces total system life cycle cost by minimizing the number of projectors by one-third to one-half the number of projectors used in competing systems. The system is compatible with a full array of fast jet and rotary wing cockpits.
“CRVS is unique because it is the only system to provide constant resolution throughout the field of view,” added McGraw. “It eliminates a key problem with other systems, where the visibility of targets varies depending on where the pilot looks. Our design provides increased performance, yet is simple in concept.”
Installation of the F-15C visual systems will begin in October 2012 and will be completed by January 2013, allowing training to start by the end of that month.

Jetro koliko je kostao taj program da se produze resursi F-15 a koliko bi kostao za J-22,koliki je broj F-15 u upotrebi koliko j-22(isplativost programa) ,kakav je avion F-15,a kakav je j-22...Na sve to dodaj i modernizaciju i stavi perfomanse same platforme na papir i pogledaj za te pare sta si dobio,a sta si mogao da kupis i onda ces shvatiti zasto sa logicne strane se to ne uradi...a tek sto mi nemamo pare za bacanje

Zašto nije zaživela mornarička verzija (sa mogućnošću poletanja i sletanja na nosač) - F-15N?
