(Any art created for this ship would have to somehow find a way to incorporate four stacks)

A contemporary of the Type 51 gunboat, the Picket was one of the last entirely pre-dreadnought combat jumpships developed by the Terran Alliance, with the design work begun in 2280, but the first hulls laid down in 2304. Though technically rendered obsolete by the innovations made with the Dreadnought, the Picket still filled the need for a "fast" fleet level escort with a jump range that, while shorter than a Dreadnought, was sufficient to keep pace with the existing heavy transports used by the Hegemony military and major shipping concerns. It was also a dedicated combat and escort ship, unlike the aging City class cruisers which currently filled the role of fast escort. This allowed designers to "cut out the fat", as it were, resulting in a leaner, cheaper, and less maintenance intensive design while retaining or exceeding most of the City's combat capabilities.

The ship's design concept shows some similarity to the Cruiser class (though thankfully not the aesthetics) due to its heavy missile based armament. Like the Cruiser (itself descended from a pre-dreadnought design) the Picket series was intended to rely on nuclear weapons for its primary hitting power, ideally engaging from well beyond normal weapons range. As a last ditch armament, the vessel also carried a few naval cannons in single mounts and turrets of smaller quick firing guns around the small craft bays. Sufficient for handling most expected opponents, but quickly rendered unimpressive as naval technology advanced. Due to fears of escalation, the expected nuclear armament was never actually used in combat by a Picket series vessel (at least not in Terran service), and even the earliest vessels would deploy with only a small number of nuclear warheads to complement their conventional missile systems, and even these warheads were removed from all ships by 2320.

The Terran Alliance (and later Hegemony) put into place plans to construct over fifty Picket series destroyers in batches of six ships, with each subsequent batch incorporating improvements and changes based on experiences with the prior designs. The first four batches were to be built using the existing jump core, while subsequent classes would incorporate a compact jump core and significant changes to the base design. In practice however, due to changing priorities and funding as well as concerns that the Picket wouldn't live up to expectations, the final order was reduced to thirty six vessels, built in batches of four (designated the A through I classes) over the next ten years, all of which were built largely to the original specifications with only minor improvements incorporated into the designs. Despite the concerns of Hegemony Admirals, the Pickets proved themselves capable fleet escorts for decades, earning another production run of twenty ships in 2317 (the J through N classes) for Hegemony service, and an additional sixty ships built for export over the subsequent twenty years, causing the Picket to spread in small numbers across the entire Inner Sphere and near periphery.

Though ultimately a successful design, the Picket series enjoyed a relatively brief period in the limelight, gradually replaced in front line Hegemony service by the Essex after 2351. Among the house fleets the Picket was able to hang on longer, but even then modern ships rendered them obsolete by the mid 25th century. The last Picket class ships saw service with the Periphery states as late as the Reunification War, most notably as command ships for groups of Taurian merchant raiders and CSS squadrons. The last of the Picket series Destroyers were finally broken up for scrap in the early 27th century.

Good news is the lab boys say the symptoms of asbestos poisoning show an immediate latency of 44.6 years. So if you're thirty or over you're laughing. Worst case scenario you miss out on a few rounds of canasta, plus you've forwarded the cause of science by three centuries. I punch those numbers into my calculator, it makes a happy face.

It's odd that a ship designed to launch nukes has NO point defenses...

Neither did the Cruiser, which was built for basically the same fighting style. Or, I think, any of the earliest generation of Hegemony warships. It would have looked out of place if the only ship to bother with point defense was a relatively low profile escort and not the big expensive prestige hulls.

One might argue that naval missiles were a relatively new technology and that their designers might have thought that it was unlikely the Alliance's own ships would come under missile attack, but that's not a great argument. Another argument might be that point defense wouldn't have provided much protection against missile attack, since each bay can only engage one missile per round until AMS were available.

Double check your ammo weights, they are a bit off.

It's a glitch with megameklab's text readout, just one I didn't catch and correct like the heatsinks and the shots per standard autocannon bay. The total number of shots is accurate and the tonnage in the actual design file is correct.

Quick question... Is this a “civilian” jumpship with a standard KF jump core or a warship masquerading as a “jumpship” with a compact KF core?

Thx.

Edit:  Nevermind, it must be a compact core, or she couldn’t afford the 3/5 thrust.

Primitive jump core with a twenty light year range. In terms of mass it's heavier than a compact core, but light enough to still allow for maneuvering and weapons.

Would quad engine nozzles like the Lola be close enough?

I feel like they'd have to be in a single column in that case, rather than having them in a two by two arrangement.

Looking over the design... I think it needs a couple tons more armor.

MML I don't believe rounds armor correctly for primitives.

236 * 0.4 = 94.4, rounded down to 94.
94 + 30 [SI provided armor] = 124
124*0.66 = 81.84, rounded down to 81.

Overall, my re-creation of it by hand is 13 tons underweight [once you increase armor tonnage by 2 to account for that]


I am assuming post-2300 weights for sails, transit drive and control systems.

It fits well with the early designs.

Sigh, it wouldn't surprise me. There always seems to be some new bug or other when it comes to armoring large spacecraft in mml.

As a writer who has lost paying assignments, I feel your pain, and will pass down my wisdom:

You must learn the ways of Google Drive and Dropbox, young padawan.

Seriously, unless your stuff is someting that you're contractually required to not put on a cloud (it happens), one or both of those services pretty well protect you from anything short of an ELE, at which point, Btech becomes academic.

I back up more often now, and more completely, so hopefully it won't happen again.  I have exactly zero trust in Google...
