SEOUL, Sept. 23 (Yonhap) -- U.S. aerospace giant Boeing is moving closer to win South Korea's 8.3 trillion won (US$7.2 billion) contract as the state procurement agency is set to recommend F-15 Silent Eagle as the sole candidate that comes within the budget in an upcoming meeting of top military officials.
The Defense Acquisition Program Administration (DAPA) has completed biddings and evaluations on three jets -- Boeing's F-15 SE, Lockheed Martin's F-35 and the EADS' Eurofighter -- and briefed President Park Geun-hye on the results earlier this month.
The DAPA said Monday it will hold a subcommittee meeting later in the day to review the evaluation process and make a final decision on Tuesday in a meeting presided by Defense Minister Kim Kwan-jin, without elaborating which jet scored the highest.
Overall, the silent eagle preforms exceptionally well in the vertical aspects of maneuverability while providing an average performance in horizontal metrics.
+exceptional T/W ratio
+excellent maximum speed
+ high rate of climb
+/- average sustained & instantaneous turn rate
+ solid acceleration performance
Avionics
F-15E upgrade road map provided by Boeing.
The base Strike Eagle's core avionics package underwent numerous
upgrades as a result of foreign contracts. For example, international
customers have become increasingly interested in acquiring the new
generation of active electronically scanned array (AESA) radars for
their fighter aircraft. The first strike eagle to receive an AESA was
the F-15SG in 2005 with the AN/APG-63(V)3. Boeing has not indicated
which radar system will be utilized in the silent eagle but the most
likely candidates are the APG-63(V)3 and APG-82(V)1. The APG-63(V)3
represents a major improvement over the original APG-70 electronically
scanned array (ESA) in terms of both performance and reliability.
APG-63(V)3:
"This is the most capable radar in a fighter aircraft in the world. The system is as advanced as that of the Air Force's most advanced fighter -- the F-22 Raptor. The AESA is all-electronic based with no moving parts on the radar system itself, allowing everything to be electronically steered. The system allows the F-15 to engage targets better and with greater reliability. The AN/APG-63(V)3 AESA radar provides powerful, adaptable radar technology, proven performance, and tactical flexibility that F-15 pilots can rely on. The (V)3 is essentially an updated APG-79 front-end (antenna and power supply) and APG-63(V)1 hardware back-end. For the F-15E, the antenna size was increased to 0.9 m (36 in.) diam, and improved tile T/R modules with a greater mean time between overhaul are used." - Global Security, 2011
APG-81(V)1 Radar
The number of transmit receiver modules (TR) featured within an AESA is generally indicative of its maximum detection range; the highest performance AESA radars feature 1,500 TR modules. The strike eagle's spacious nose cone allows it to accommodate large 1,5000 element arrays such as the APG-63(V)3 and APG-82(V)1. Either system will greatly enhance the F-15SE's ability to detect low observable targets at a distance. The APG-82(V)1 is the more modern of the two systems and delivers comparable performance at a lower cost.
"The APG-82(V)1 optimizes the F-15E’s multirole mission capability. In
addition to its extended range and improved multi-target track and
precision engagement capabilities, the APG-82(V)1 offers a more than
twentyfold improvement in system reliability over the legacy F-15E
APG-70 radar. The new radar works as a plug-in-play system with newer,
easily replaceable parts...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." - Global Security, 2011
