Dette flyet fremstår fremdeles som veldig vakkert, og vi som har hatt gleden av å fly det elsker det. Det var et sjokk å komme hjem fra USA til T-33 på Sola hvor vi måtte lære antikke prosedyrer (aural null) og til og med morse..... Hvorfor moddes disse flyene? Jo, fordi T-7 synes å være en del forsinket. Dessuten vil en del fly få et liv etter T-7s inntreden.

The Attitude and Heading
Reference System (AHRS) for the 53 Air Force T-38A and eight AT-38B training
jets needs replacing, according to the Air Force Life Cycle Management Center’s
T-38 program office (AFLCMC/WLD) at Hill Air Force Base, Utah.
“The T-38A and AT-38B
Attitude [and] Heading Reference System (AHRS) reliability has diminished to a
point of concern,” a representative for AFLCMC/WLD wrote in an emailed
statement. “Spare parts for repairs are difficult to procure and the system
requires replacement.”
Yet, the Air Force has
included no funding for AHRS replacement in its Fiscal 2021 budget request.
“The program has not been
funded,” according to AFLCMC/WLD. “When it is funded, an [Request for
Proposals] RFP will be issued.”
AHRS subsystems under
consideration for replacement are the 1960s era displacement gyro by L3
Technologies [LHX] and Honeywell [HON]; the attitude
director indicator by Astronautics, MOOG [MOG.A]
and Joint Electronics; and the horizontal situation indicator by
Astronautics and Joint Electronics.
In addition to the 53 T-38s
and 8 AT-38Bs, which retain analog gauge cockpits, the Air Force has 442
T-38Cs, which have more modern “glass cockpits” from the late 1990s.
Northrop Grumman [NOC] built the T-38 Talons, which entered service in 1960, and
which are to be replaced by the Boeing [BA]-Saab T-7A
Red Hawk. Air Force officials have said they expect the T-7A Red Hawk,
named to honor the Tuskegee Airmen, to reach initial operating capability by
2024 and full operational capability by 2034. The Air Force said that it
designed the T-38s for 7,000 hours of service life and that the aircraft are in
their third service life, sustained by upgrades and service life extensions.
Like the T-38As and
AT-38Bs, the T-38Cs also face Diminishing Manufacturing Sources Material
Shortfalls (DSMS), caused by the stoppage of parts production.
Because of DSMS and
termination of parts support from Original Equipment Manufacturers (OEMs), the
Air Force is moving to a T-38C mission display processor by Aitech;
an Elbit America head-up display paired with a Leonardo upfront
control panel; and a very high frequency communication radio by Cobham
Aerospace Communications.
“Also, the T-38C is facing
display system DMSMS issues,” according to AFLCMC/WLD. “The OEM [L3Harris] is
moving to a more modern touch screen and large area displays vice the
1990s/2000s Video Graphics Arrays, Super Video Graphics Arrays and Active
Liquid Crystal Matrix displays.”
L3Harris built the T-38C
electronic engine display and multi-function displays.
“Due to component
obsolescence and supportability issues the [T-38C] displays will not be
supported beyond 2026,” AFLCMC/WLD said. “The Air Force intends to maintain
current functionality to the greatest extent possible with electronic engine
display and the multi-function display replacements, and there is no intention
to integrate touch screens or large area displays as part of the replacement of
those displays.”
