Engineering technology

Construction equipment

Laser drill

• Laser-based drilling technology commonly used in constructing underground chambers and networks for asteroid or planetside bases (SCE Short Story: "Foundations, Book One"; TNG: "Home Soil")
• Mark III implementation developed by 2265 (SCE Short Story: "Foundations, Book One")

Plasma drill

• Plasma-based drilling technology used for areas with especially dense strata (DIS Novel: Desperate Hours)
  • More powerful alternative to laser drills

Handheld tools

EPS pattern tracer

• Engineering tool (DS9 Novel: Mission Gamma: Cathedral)
• Presumably used to detect faults in EPS conduits

P-38

• Emits a broad range of sound and light frequencies in order to open wedged panels (SCE Short Story: "Interphase, Part Two")
• Also produces magnetic field emissions to counteract magnetic seals, often allowing for opening of sealed doors or compartments (TNG Novel: Available Light)
• In use by mid-23rd century (TOS: "The Trouble with Tribbles")
  • Per annotations of "Many Splendors"

Power plants

PXK fission reactor

• Still in use by mid-23rd century (SCE Short Story: "Foundations, Book 1")
