Protective shielding
Protective shielding was a defensive armor aboard  shuttlecraft, which protected viewports in an emergency.

In 3190, when UFP-11 was disabled by a rogue gamma-ray burst and lost navigational control, the shuttle deployed protective shielding over the viewports. Once the shuttle had crash landed on Kokytos, Lieutenant Sylvia Tilly retracted the shielding to see the landscape. ()

Later that year, shuttlecraft DSC-09 deployed its protective shielding to protect from asteroid debris while travelling through the ionosphere of Species 10-C's homeworld. ()
