Oh, and if the Imperium really was TL 16 in 1116, then I'm sore at GDW and DGP for not providing a long list of TL 16 equipment

There are a few TL 16 weapons listed and there may be a few TL 16 dinguses I've forgotten about, but that's about it.
Hans
It's not like there's a lot of TL15 equipment listed, either.
Looking at MT IE, the following items have TL15 entries;
underlining indicates introduced at that TL.
Bug Detector,
Handheld Densitometer, Rope,
NAS,
Bioscanner, Vacc Suit, Tailored Vacc Suit, FGMP.
And for TL16:
FGMP,
Plasma Rifle,
Neural Pistol,
Neural Rifle
In the MT RM, we get some other additions of note:
TL 15: Fusion PP, Fuel Cells, Storage Batteries,
Jump 6, Avionics,
Meson Comms, Radio Comms, Laser Comms, Maser Comms, Radio Jammers, Densitometers, Neutrino Sensors, NAS, Holorecorder, Spinal PA H/P/T, Spinal Meson J/R/T,
50Td Meson Bay, 100Td Missile/PA/Rep bays, 50Td Missile/PA/Plasma/Fusion/Repulsor Bays, PA Turrets, RPA/RPB/RPC Plasma Guns, RFX/RFY/
FZ Fusion Guns, Point Defense Targeting Systems, Screens ...
TL 16: Fusion PP, Storage Batteries, Avionics, Meson Comms, Radio Comms, Laser Comms, Maser Comms, Radio Jammers, Densitometers, Neutrino Sensors, EMS Arrays, Spinal PA U, Spinal Meson U, 100Td Missile/PA/Repulsor/Meson/
Tractor bays, 50Td Missile/PA/Plasma/Fusion/Repulsor Bays, Beam Laser Turrets, PA Turrets, Plasma Turrets, Sand Turrets, HE, KEAP rounds, RFX/RFY/
RFZ Fusion Guns, Point Defense Targeting Systems, Screens ...
TL17:
Coherent Superdense Armor, AM PP, Storage Batteries,
Reduced Jump Fuel, Avionics, Meson Comms, Radio Comms, Laser Comms, Maser Comms, Radio Jammers, Spinal PA V, Spinal Meson V/X,
Spinal Disintegrator A, 100Td Missile/PA/Repulsor/Meson/Tractor bays, 50Td Missile/PA/Plasma/Fusion/Repulsor Bays, Fusion Turrets, Screens, ...
So there's plenty - but it's almost all heavy weapons. I omitted the screens - but every kind of screen has entries for TL15/16/17 except white globes.
Oh, Fuel Purification and Computers continue to get better, too.
DGP's take on Tech Levels in the core seems to have been that many worlds had a few areas of TL 16 capability even in 1100... but that by 1116, a number of them had actually been implementing it widely enough to matter.
Grand Census broke out TL's before MT was published... based upon the categories in the CT TL tables.
