Tesla Model S Plaid can achieve 1.2G in horizontal acceleration... which is what produces the Tesla Smile™ you see in all those videos of people (and children in the backseats) enjoying what happens when you "stomp the pedal" with the acceleration setting dialed in to "Ludicrous" mode.

I know, electric cars can have very high acceleration - the fact remains that very very few aircraft can achieve a thrust of 1g plus.
Spinward Flow

That's the advantage of solid-friction-solid contact thrust compared to fluid flow propulsion thrust.
One of the banes of aircraft design is that pretty much ALL aircraft "gain weight" after they're initially introduced into service. There's always efforts to "add more stuff" onto already existing (known working and bought) hardware in order to enhance and add new capabilities. This is why "new" aircraft need to be designed with an excess weight margin built in from the start so as to leave room for future upgrades and later developments (which ALWAYS gets eaten up!).
The fact that those later add on capabilities "cost and weigh like solid gold" is surely just a side effect of the business model.

One hundred twenty percent represents local gravity field plus thrust.
More distinctive in space, on a tail sitter with a non gravitated hull.

Pity we can't stretch our spacecraft primary hulls.

There was a stretched serpent class scout or merchant in one of the PP supplements - will have to go find it.

Trillion Credit nixes (major) hull alterations.

So ignore it. TNE has ships welded together

Welding differs from stretching; basically, you're gluing them together.
To be fair, I'm was more interested in adding, subtracting, or changing hull armour.

The extended Scout (Wind-class) and the matching Free Trader were presumably purpose build, not refits.
They are listed as products of the company Delta Research.

It could be it's stretched because the hull is customized, the plug(s) being inserted during construction, rather than a refit.
For Mongoose Traveller 1e, Avenger's Golden Age Starships 5: Archaic Small Craft and Space Stations (also included in the Golden Age Starships Compilation) has rules for reaction rockets. It also expands small craft design down to TL6 so small capsules can be put on top of those rockets.
It is also here in the srd: http://www.travellersrd.com/content...high_guard_srd/spacecraft_options.html#drives

Was the rocket equation used at all to determine the fuel requirements for those rockets?
Indeed probably not, and from an engineering standpoint, engines transform the energy in the fuel into physical work. So that anytime anyone feels like sitting down and calculating fuel amounts, it would be optimal to start with the amount of energy in the fuel, and figuring to rocket equation, carnot cycle and such into it imo.
Which will quickly lead to “REALITY” where ships are either ALL FUEL or drives are SUPER BEAM WEAPONS or fuel is stored as a PLANET BUSTING BOMB (Energy Density). In “Traveller meets Reality“ terms, you build a Dreadnaught to land a Launch on Mars … in only a few months to years travel time.
Next you'll be saying someone is going to be making an "atomic" bomb or something.

Here is some World War 2 era data on guided missiles and rockets, so Tech Level 5 and 6.
Hopefully, that will keep people busy for a while.
