Sandia national laboratories is
america's one-stop shop for nuclear
stockpile design engineering and
maintenance. The company is currently upgrading the
united states B-61 nuclear gravity bomb
to the b-6112 standard. Scandia explained the B-61's life
extension program as a program that
allows scientists and engineers to
address the aging of nuclear weapons
components. Some components are
re-qualified and go back into a weapon
without change. Others that have aged or remanufactured
using the original specifications and
sometimes the original technology is no
longer available, so sandia redesigns
those parts using modern technology.
The B-61 originally entered service with
the united states in 1968 and this
latest refurbishment is expected to
extend the B-61 service life for an
additional 20 years. The B-61 is one of just two free falling
or dumb bombs that the united states
currently keeps as is the smaller of the
two
and though both are nuclear the B-61 is
more accurate than the larger B-83, making the B-61 more of a scalpel than a
sword.
The smaller explosive force of the B-61
makes it more of a tactical weapon and
would offer more operational flexibility
due in part to the lower amount of
nuclear fallout the bomb would create
and the more precise nature of its
explosion. The B-6112 has been flight tested on
other platforms as well. The F-15E strike eagle was cleared for
flight with the B-6112 after a
successful test in march as was the air
force's B-2 bomber earlier this summer.
What made the F-35 flight test unique
however was the jets stealth features. In order to leave the D-35 stealth
capabilities intact measured by the jets
radar cross-section ordinance as carried
in an internal bomb bay. According to sandia this most recent
flight test was a first in two areas.
The first B-6112 from an internal bomb
bay, as well as the first supersonic, mach
one plus drop test. Though the B-61 upgrade program has
legitimate criticisms first and foremost
cost and realistic combat utility it
won't go away anytime soon
and since they'll be around for at least
20 more years it just makes sense to
clear them for duty with one of the
world's most capable stealth
30 platforms.
