F-15SE Silent Eagle is an upgraded version of the F-15 Strike Eagle aircraft, being developed by Boeing for international customers. The F-15SE features an innovative design which reduces its radar cross section. A prototype of the F-15SE Silent Eagle aircraft was first unveiled in March 2009. The F-15SE flight demonstrator aircraft, F-15E1, completed its maiden flight in July 2010.
F-15E ‘Strike’ Eagle: Details
F-15SE Silent Eagle design
F-15SE is 63.6ft (19.4m) long, 18.5ft (5.6m) high and has a wingspan of 42.8ft (13m). The basic design of the F-15SE is similar to that of the F-15 Strike Eagle aircraft with new components added. The new components include the conformal weapons bay (CWB) instead of the standard conformal fuel tanks.
The CWB significantly increases the internal carriage capacity of the aircraft and also reduces its radar signature. Two additional weapons stations have been included to enable the aircraft to carry an additional four air-to-air missiles.
The Silent Eagle also features twin vertical tails canted 15° outward. Canted tails provide rear lift to the aircraft and reduce ballast usage, while increasing the range by 75 to 100 nautical miles. Coatings will also be applied to various areas of the aircraft to minimise the radar signature.
Canted Tail Fins
Twin vertical tails canted 15° outward
The Strike Eagles tails are canted outward by 15 degrees which decreases RCS in A/A engagements. The outward cant also improves aerodynamic efficiency and generates extra lift. The canting also allows airframe weight to be reduced by removing 400-500 lbs of ballast weight from the forward section of the aircraft. Source onfinalofficial.wordpress.com
The F-15SE has also been designed to function as a non-stealthy, multirole aircraft. The CWBs can be removed and the aircraft can be reconfigured to include conformal fuel tanks based on mission requirements.

F-15SE Silent Eagle development programme
Boeing commenced development of the F-15SE as an evolution to the F-15 family of aircraft. The company signed a Memorandum of Understanding with Korea Aerospace Industries in November 2010 for development of the F-15SE’s CWB.
F-15 Silent Eagle: Why South Korea rejected this jet: Here
Boeing’s F-15 Silent Eagle had been in the box seat to win the 8.3 trillion won ($7.7 billion) tender – as the only bid to fall within budget – but former military top brass and even the ruling party’s lawmakers had criticized the plane as it lacked crucial stealth capabilities.
Note: If one looks at the cost of the F-15E one needs not wonder why the F-15SE did not get any buyers as it would cost nearly the same as the F-35 which would be around $400 million a unit…The F-15E cost Qatar $293 million per unit….

F-15E1 flight demonstrator aircraft
The Boeing company completed the first flight of the F-15SE ‘Silent Eagle’ flight demonstrator on July 8, 2010. The aircraft, designated F-15E1 took off from the Lambert St. Louis International Airport on an 80-minute flight, where the aircraft opened and closed its left-side Conformal Weapons Bay, which contained an AIM-120 Instrumented Test Vehicle (ITV) missile. “[In this flight] we cleared the desired flight envelope needed to fire the missile at the test range” said Boeing F-15 Chief Test Pilot Dan Draeger. According to Boeing F-15 Development Programs Director Brad Jones, in the next couple of weeks, the F-15E1 will be ferry to a test range to launch an AIM-120.
Key to the F-15SE design is the conformal weapons bays, designed for the F-15SE. This new add-on module was originally designed specifically for the F-15SE but could also be available for other F-15 models, particularly interesting is the F-15E, I K, S and S (F-15E models operated by Israel, South Korea, Saudi-Arabia and Singapore) already operating F-15s with conformal tanks.
F-15SE conformal weapons bays
The Silent Eagle was developed in response to South Korea’s requirements for high-performance, stealth capable fighter aircraft. The F-15SE offers unique aerodynamic, avionic and Radar Cross Section reduction features that provide maximum flexibility in air dominance as it can be operated with and without stealth capabilities. Boeing is offering the F-15SE with customizable fighter that can be outfitted with AESA radars, radar absorbent coatings, large digital cockpit displays, fly-by-wire software, canted tails and bolt-on internal weapons bays.
According to UPI, Boeing is hoping to win an export license to sell its new F-15 Silent Eagle to South Korea within a month. South Korea has a requirement for a third batch of 60 F-15 size fighters, due next year. Boeing could be offering the F-15SE with customizable fighter that can be outfitted with AESA radars, radar absorbent coatings, large digital cockpit displays, fly-by-wire software, canted tails and bolt-on internal weapons bays.

Boeing has offered the aircraft for the F-X III competition launched by South Korea’s Defense Acquisition and Procurement Agency to procure 60 new fighter aircraft for the Republic of Korea Air Force. The F-15SE is competing for the $7.3bn order with the Eurofighter Typhoon and Lockheed Martin’s F-35.
The three companies submitted their formal bids in June 2012. South Korea was scheduled to decide the winner of the competition in October 2012 but the decision has now been postponed to mid-2013.
New orders from Saudi Arabia and Japan are also the driving forces behind the development of the next generation of F-15 aircraft. The development cost of F-15SE is estimated at $100m each. Boeing plans to offer the aircraft to five foreign customers with an estimated market for 190 orders. Flight testing of the F-15SE is expected to be carried out in 2013.

The F-15SE will feature next-generation Joint Helmet Mounted Cueing System produced by Vision Systems International, Elbit 11in x 19in Large Area Display (LAD) system on the front and rear cockpits, digital fly-by-wire flight control system, Link-16 Fighter Data Link and infrared search and track (IRST) system.
Joint Helmet Mounted Cueing System (JHMCS)
In an air-to-air role, the JHMCS, combined with the AIM-9X missile, form the High-Off-BoreSight (HOBS) system. HOBS is an airborne weapon-interception system that enables pilots to accurately direct or “cue” onboard weapons against enemy aircraft merely by pointing their heads at the targets to guide the weapons, while performing high-G aircraft maneuvers that may be required to complete the attack.
In an air-to-ground role, the JHMCS is used in conjunction with targeting sensors (radar, FLIR, etc.) and “smart weapons” to accurately and precisely attack surface targets. It allows F-15E aircrew to provide unparalleled support to ground troops in the CAS environment.
In all roles, the JHMCS provides the pilot with aircraft performance, targeting, weaponry and threat warning information, regardless of where the pilot is looking, significantly enhancing pilot situation awareness throughout the mission. In a dual-seat aircraft, each crewmember can wear a JHMCS helmet, perform operations independent of each other, and have continuous awareness of where the other crewmember is looking.
Unlike one of its predecessor, the DASH system, which is integrated into the helmet itself, JHMCS is a clip-on attachment unit, which can be latched into position with one hand during flight (see photo below). It fits to modified HGU-55/P, HGU-56/P or HGU-68/P helmets and it features a newer, faster digital processing package than that used in the DASH. The overall design is more advanced than DASH, based on the collective knowledge accumulated by Elbit and Kaiser through the years.
The JHMCS has a magnetic helmet-mounted tracker (like DASH), which determines where the pilot’s head is pointed, combined with a miniature display system that projects information onto the pilot’s visor. A magnetic transmitter unit is fixed to the pilot’s seat and a magnetic field probe is mounted on the helmet to determine where the helmet is actually pointing. A Helmet Vehicle Interface ( HVI) interacts with the aircraft system bus to provide signal generation for the helmet display. The head tracker and visor display together act as a targeting device that can aim sensors and weapons.
To obtain a variety of information and sensor-based data pilots can refer to the visual display on the inside of the helmet while remaining in a “heads-up” or “outside” position during combat; this eliminates the break in visual contact that occurs when they look away to check the display readouts in the cockpit. This significantly improves pilot situational awareness during all mission elements. The visor display presents monochrome calligraphic symbology (stroke display) with information like airspeed, altitude, G-load, AoA, target range, targeting cues, threat warnings, etc. JHMCS provides support for raster scanned imagery to display FLIR or IRST pictures for night operations and provides collimated symbology and imagery to the pilot. JHMCS symbology covers a 20 degree field of view for the right eye, with an 18 mm exit pupil (see photo below).
To aim and fire a missile, pilots simply move their heads to align a targeting cross (placed in the middle of the projected imagery) with the target and press a switch on the flight controls to direct and fire a weapon.
To attack a ground target, the pilot can acquire the target with a sensor and note it’s location on the helmet display. Alternatively, the pilot can use the helmet display to cue sensors and weapons to a visually detected ground target. Note that precision ordnance cannot be released based on JHMCS targeting alone, the system is not accurate enough for this. However it can be used to direct the aircraft’s much more precise targeting systems (targeting pod) towards the target the pilot is looking at. This way the tedious “soda-straw” search limited to a display image generated by the narrow field of view targeting system can be shortened significatly. With JHMCS, target acquisition can follow a much quicker “look, sharpen, shoot” process.
The system can be used without requiring the aircraft to be maneuvered, significantly reducing the time needed to prosecute an attack, which also minimizes the time spent in the threat environment.
Since targets may be located at high-off-boresight line-of-sight locations in relation to the shooter, the system delivers a short-range intercept envelope that is significantly larger than any other air-to-air weapon in use. When combined with the AIM-9X missile, JHMCS allows effective target designation up to 80 degrees either side of the aircraft’s nose.
The JHMCS display assembly requires two cable connections: a high voltage power cable for operation and a data cable for information exchange with the host aircraft. Unlike in DASH the high voltage power supply is not embedded in the helmet, it feeds up via an umbilical, through a quick disconnect inline high coltage rated connector.
When used in conjunction with a datalink, the system permits handoff of visually detected targets from one aircraft to another, with the second aircraft receiving visual cueing to the target. Source f-15e.info

IRST21 infrared sensor
IRST21 is the next generation of Lockheed Martin’s legacy IRST sensor system, which accumulated over 300,000 flight hours on F-14 and international F-15 platforms. As a passive, long-range sensor system, IRST21 uses infrared search and track technology to detect and track airborne threats with weapon-quality accuracy, increasing pilot reaction time and improving survivability.
A compact design enables IRST21 to be integrated in a variety of ways. On the F/A-18E/F, IRST21 is mounted on the nose section of the centerline fuel tank. A podded sensor system with IRST21 is also in development and will be transportable across a wide range of platforms including the F-15C and F-16. Source lockheedmartin

APG-82(V)1 AESA radar
Delivering next-generation capabilities
The APG-82(V)1 AESA radar is the latest radar advancement for the U.S. Air Force F-15E fleet.
F-15E PLATFORM OPTIMIZATION
The APG-82(V)1 optimizes the F-15Es multirole mission capability. In addition to its extended range and improved multi-target track and precision engagement capabilities, the APG-82(V)1 offers improvement in system reliability over the legacy F-15E APG-70 radar. This phenomenal level of reliability and maintainability will result in significant maintenance cost savings for the U.S. Air Force.
By leveraging combat-proven technologies—the APG-79 and APG-63(V)3 AESA radars flying on the F/A-18E/F, the EA-18G and the F-15C platforms—Raytheon delivers a low-risk, cost-effective and superior situational awareness and attack radar to modernize the Strike Eagle.
EFFECTIVENESS AND SURVIVABILITY
Aircraft equipped with the APG-82(V)1 AESA radar can simultaneously detect, identify and track multiple air and surface targets at longer ranges than ever before. The longer standoff range facilitates persistent target observation and information sharing for informed decision making. This superior battlespace awareness supports greater tactical mission capability. The result: greatly increased aircraft-aircrew effectiveness and survivability.
PROVEN AESA TECHNOLOGY
Raytheon’s ground-breaking AESA technology has consistently proven its exceptional performance, reliability and mission capabilities for the warfighter. Our APG-79 AESA radar design, now extended to the APG-82(V)1, is combat-proven on fielded F/A-18s, and it’s being adapted now to modernize the Strike Eagle.
“The new radar system does everything faster, is extremely precise and requires less maintenance,” Riley said. “It can designate air-to-air and air-to-ground simultaneously, allowing us to track enemy aircraft and identify ground targets at the same time.”
According to the Air Force’s first RMP report, the new radar system is designed to retain functionality of the old legacy radar system while providing expanded mission employment capabilities to include:
– Near simultaneous interleaving of selected air-to-air and air-to-ground functions
– Enhanced air-to-air and air-to-ground classified combat identification capabilities
– Longer range air-to-air target detection and enhanced track capabilities
– Longer range and higher resolution air-to-ground radar mapping
– Improved ground moving target track capability
An advanced targeting pod provides the aircraft with target identification and autonomous tracking capabilities. A navigation pod will also be fitted to the aircraft providing it with all-weather and night-attack capabilities.
The aircraft will also feature advanced electronic equipment including BAE Systems digital electronic warfare system (DEWS) and active electronically scanned array (AESA) radar.
BAE Systems digital electronic warfare system (DEWS)
Instead of the tactical electronic warfare system (TEWS) in the Strike Eagle the Silent Eagle makes use of BAE’s Digital Electronic Warfare System (DEWS)
DEWS uses digital radio-frequency memory (DRFS) technology which is said to have substantially better performance and reliability than the Analog TEWS system. The system has the ability to listen over a frequency band constantly without the need to scan it and the advanced antenna systems can obtain more accurate data with regards to the measurement of bearings. Targets acquired by the DEWS are fused with radar and infrared search and track (IRST) data and displayed on the large format cockpit displays.
The system was designed by implementing lessons learned during the development of the electronic warfare systems for the F-22 and F-35 JSF.
The F-15 Silent Eagle’s (F-15 SE) Basic Sensor Suit
The system utilizes various sensors located in sections of the tail fins, wings and the underside of the airframe as well as a digital radar warning receiver (RWR). The Silent Eagle also contains an advanced jamming system which according to Boeing, allows the aircraft to jam enemy radar systems while still allowing it’s own radar and RWR to operate.
The actual systems contained within the Silent Eagle make it more than capable of entering the battle arena with the best of Russia or anyone else. Source onfinalofficial.wordpress.com

M-61A1 20mm Gatling gun
M-61A1 20mm Gatling gun
The M61 20mm Vulcan is an externally powered, six-barrel, rotary-fire gun having a rate of fire of up to 7200 spm. The firing rate is selectible at 4,000 spm or 6,000 spm. The gun fires standard electrically primed 20mm ammunition. The M61A1 is hydraulically or ram-air driven, electrically controlled, and uses a linkless ammunition feed system.
Each of the gun’s six barrels fires only once during each revolution of the barrel cluster. The six rotating barrels contribute to long weapon life by minimizing barrel erosion and heat generation. The gun’s rate of fire, essentially 100 rounds per second, gives the pilot a shot density that will enable a “kill” when fired in one-second bursts.
M-61A1 20mm Gatling gun on F-15C
The M61 20mm cannon is a proven gun, having been the US military’s close-in weapon of choice dating back to the 1950s. The F-104, F-105, later models of the F-106, F-111, F-4, B-58, all used the M61, as does the Air Force’s F-15 , F-16 and F-22, and the Navy’s F-14 and F/A-18. The internally mounted 20mm cannon system is common to all versions of the F-15. This system combines the widely used (F-4, F-16, F-18) M61 cannon with 940 rounds (A through D models) or 500 rounds (E model) of ammunition. The cannon can be loaded with target practice, armor piercing, or high explosive incendiary rounds. The primary use of the cannon is in the extremely short range (less than 2000 feet) air-to-air environment, where more sophistacated air-to-air missiles are ineffective. Alternately, the cannon has limited usefulness in a ground strafing role. Source fas.org
AIM-9L/M infrared-guided Sidewinder
AIM-9L Sidewinder air-to-air missiles
The AIM-9L added a more powerful solid-propellant rocket motor as well as tracking maneuvering ability. Improvements in heat sensor and control systems have provided the AIM-9L missile with an all-aspect attack capability and improved guidance characteristics. The L model was the first Sidewinder with the ability to attack from all angles, including head-on. An improved active optical fuze increased the missile’s lethality and resistance to electronic countermeasures. A conical scan seeker increased seeker sensitivity and improved tracking stability. The AIM-9L is configured with an annular blast fragmentation warhead. Production and delivery of the AIM-9L began in 1976.
AIM-9M Sidewinder air-to-air missiles
The AIM-9M missile utilizes a guidance control section with counter-countermeasures and improved maintainability and producibility. The AIM-9M is configured with an annular blast fragmentation warhead. Currently the only operational variant, has the all-aspect capability of the L model, but provides all-around higher performance. The M model has improved defense against infrared countermeasures, enhanced background discrimination capability, and a reduced-smoke rocket motor. These modifications increase ability to locate and lock-on a target and decrease the missile’s chances for detection. Deliveries of the M model began in 1983. Source fas.org
The AIM-7 Sparrow is a radar-guided, air-to-air missile with a high-explosive warhead. The versatile Sparrow has all-weather, all-altitude operational capability and can attack high-performance aircraft and missiles from any direction. The AIM/RIM-7 series is a semiactive, air-to-air, boost-glide missile, designed to be either rail or ejection launched. Semiactive, continuous wave, homing radar, and hydraulically-operated control surfaces direct and stabilize the missile on a proportional navigational course to the target. Propulsion for the missile is provided by a solid propellant rocket motor.
AIM-7F Sparrow is a supersonic, medium range, aerial-intercept missile
The AIM-7F joined the Air Force inventory in 1976 as the primary medium-range, air-to-air missile for the F-15 Eagle. The AIM-7F was an almost completely new missile, gaining ability from improved avionics that allowed the warhead to be moved to the front, allowing a bigger motor to be carried that has improved range.
AIM-7M Sparrow is a supersonic, medium range, aerial-intercept missile
The AIM-7M, the only current operational version, entered service in 1982. It has improved reliability and performance over earlier models at low altitudes and in electronic countermeasures environments. It also has a significantly more lethal warhead. The latest software version of the AIM-7M is the H-Build, which has been produced since 1987 and incorporates additional improvements in guidance. AIM/RIM-7M DT and OT was successfully completed in FY82. The F-15 Eagle and F-16 Fighting Falcon fighters carry the AIM-7M Sparrow. Source fas.org
AIM-120 AMRAAM Slammer
The AIM-120 advanced medium-range air-to-air missile (AMRAAM) is a new generation air-to-air missile. It has an all-weather, beyond-visual-range capability and is scheduled to be operational beyond 2000. AMRAAM is a supersonic, air launched, aerial intercept, guided missile employing active radar target tracking, proportional navigation guidance, and active Radio Frequency (RF) target detection. It employs active, semi-active, and inertial navigational methods of guidance to provide an autonomous launch and leave capability against single and multiple targets in all environments.
The AMRAAM weighs 340 pounds and uses an advanced solid-fuel rocket motor to achieve a speed of Mach 4 and a range in excess of 30 miles. In long-range engagements AMRAAM heads for the target using inertial guidance and receives updated target information via data link from the launch aircraft. It transitions to a self-guiding terminal mode when the target is within range of its own monopulse radar set. The AIM-120 also has a “home-on-jam” guidance mode to counter electronic jamming. With its sophisticated avionics, high closing speed, and excellent end-game maneuverability, chances of escape from AMRAAM are minimal. Upon intercept an active-radar proximity fuze detonates the 40-pound high-explosive warhead to destroy the target. At closer ranges AMRAAM guides itself all the way using its own radar, freeing the launch aircraft to engage other targets.
Presently, there are three series of AMRAAM: AIM-120A, AIM-120B, and AIM-120C.
AIM-120A. First production AIM-120A, delivered by Hughes in 1988 to the 33d TFW at Eglin AFB, Florida.
AIM-120B and AIM-120C versions are currently in production, the latter with smaller control surfaces to permit increased internal carriage capability in the F-22. AIM-120B deliveries began in FY 94, and AIM-120C deliveries began in FY 96.
P3I. An improvement program seeks to develop AMRAAM capabilities, including software reprogrammability, advanced counter-countermeasures, and options for improved propulsion.
The AIM-120A is a non-reprogrammable missile (requires a hardware change to upgrade the missile software). The AIM-120B/C is reprogrammable through the missile umbilical using Common Field-level Memory Reprogramming Equipment (CFMRE). The AIM-120C has smaller aero surfaces to enable internal carriage on the Air Force F-22 aircraft. The USAF All-Up-Round (AUR) container houses an internal cable which enables up to four missiles to be reprogrammed while in the container. USN containers are not equipped with the cable and must be opened to reprogram the missile. All three AMRAAM variants are currently approved for use on the F-15C/D/E, F-16C/D, and F/A-18C/D aircraft.

AGM-158 Joint Air to Surface Standoff Missile (JASSM)
JASSM is a precision cruise missile designed for launch from outside area defenses to kill hard, medium-hardened, soft, and area type targets. The threshold integration aircraft are the F-16, B-52, and F/A-18 E/F, and the airframe design is compatible with all JASSM launch platforms: the B-52H, F-16C/D, F/A-18E/F, F-15E, F-117, B-1B, B-2, P-3C and S-3B. The weapon is required to attack both fixed and relocatable targets at ranges beyond enemy air defenses. After launch, it will be able to fly autonomously over a low-level, circuitous route to the area of a target, where an autonomous terminal guidance system will guide the missile in for a direct hit. The key performance parameters for the system are Missile Mission Effectiveness, range, and carrier operability.

JASSM’s midcourse guidance is provided by a Global Positioning System (GPS)-aided inertial navigation system (INS) protected by a new high, anti-jam GPS null steering antenna system. In the terminal phase, JASSM is guided by an imaging infrared seeker and a general pattern match-autonomous target recognition system that provides aimpoint detection, tracking and strike. It also offers growth potential for different warheads and seekers, and for extended range. Source fas.org
The F-15E is the first aircraft to be armed with the Boeing GBU-39 GPS-guided 113kg (250lb) small diameter bomb. Up to 12 bombs can be carried. The SDB entered Low-Rate Initial Production (LRIP) in April 2005 and achieved Initial Operating Capability (IOC) on the F-15E in September 2006.

The Laser Small Diameter Bomb (Laser SDB) system is the next generation of affordable and low-collateral-damage precision strike weapons, which builds on the success of the same Semi-active Laser (SAL) sensor currently used by Boeing’s Laser JDAM. A Laser SDB increases mission effectiveness in several ways:
By using already-proven laser sensor technology, Laser SDB offers the flexibility to prosecute targets of opportunity, including moving targets. With the BRU-61 Carriage System, these optimized munitions offer increased load-out for each weapons station to prosecute multiple targets per sortie. As a 250-lb. class weapon, Laser SDB’s smaller size and High Performance Wing Assembly allow it to glide for extended ranges.
Besides providing a safer standoff distance for pilots at greater than 60 nautical miles, Laser SDB target coordinates can be updated after weapon release by illuminating the target with standard Laser designation procedures. Laser SDB also retains a smaller warhead that provides reduced collateral damage, and offers ultra-low fragmentation with the composite focused lethality munition (FLM) variant. Source boeing.ca
