You really need to join the NS draftroom.

Check my sig.

I signed up; just waiting for my email to be validated.
How bad do these designs look? I'm particularly curious about my two-hull battlecarrier design...

All I can say to that is the era of lol superdreadnought and supercapital designs of NS thankfully died in 07.

Hooray! So, it's more of a missile spam era? Good, that means lots of arsenal ships and aegis ships and so on...

Well, now I'll just have to redesign the stand-in for the Sea Shadow.

It all depends on who you rp with... naturally. The average player will launch 13,000 missiles at you :P, without regard to other things.

Fair enough.

revised!

M1500 Monster
Some say the era of big-gun artillery is over. The Monster disagrees. The M1500 Monster, armed with a 12" (304.8mm) howitzer, can deliver shells (including cluster munitions or laser-guided shells) 50000-78000m downrange. It is self-propelled, with torsion-bar suspension, and carries three shells; a separate ammunition vehicle carries spares.

Weight: 55 tons (50 tonnes)
Length: 16.5m
Width: 3.5m
Height: 3.5m
Powerplant: Perkins 1200hp diesel
Armament: 12" (304.8mm) Mk. 12 howitzer (3 shells); 12.7mm M2HB AAMG (2000 rounds)
Armor: 13mm max
Range: 523km (325 miles)
Speed: 55km/h (34 mph)
Crew: 7 (driver, 2 gunners, 4 loaders)

Mk. 12 Howitzer
The weapon behind the Monster, this is a 12" (304.8mm) long-range howitzer.

Shell types: Laser-guided, cluster munitions, rocket-assisted projectile, AP, HE
Max range: 50km (normal); 78km (RAP)

All I can say to that is the era of lol superdreadnought and supercapital designs of NS thankfully died in 07.

...and thank @#*$ for that! I swear if I heard 1 more "nautical engineer" tell me it was possible...

Anyway, back on topic, designs look good to me. Just wondering how you're fitting 6 VLSs onto a ship only 100m longer than a Ticonderoga Class, which has only 2. That will be your first problem in the draft room I should think.

Six may be a little excessive, on second thought. Three makes more sense.
The displacement's probably too big. No battleship guns, no battleship armor. Would 12000-15000 tons make sense?

All designs here have been appropriately modified, and are now on offer.
Please choose six of the following design proposals -
ATGM, carrier, SWATH patrol boat, flying wing fighter, flying wing bomber, cruise missile, hydrofoil transport, hydrofoil patrol boat, pure arsenal ship, missile carrier, stealth fighter, or fighter

How's this? Also, is anyone even on the Draftroom any more?

T-4 Lynx
The Lynx is our first tank to mount a electro-thermal-chemical gun. It is armed with the Mk. 14 105mm ETC gun, which is based on the venerable M68 rifled 105mm gun. Its armor protection scheme consists of a sloped, composite matrix of laminated ceramic-nickel-steel alloy, providing RHAe of 720mm. Powered by the GD883 V12 water-cooled diesel, the Lynx has respectable performance, and features helical spring suspension.

Weight: 52 tonnes (57.3 tons)
Length: 7.3m (23'11.4"); with gun, 9.068m (29'9")
Width: 3.74m (12'3")
Height: 2.50m (8'2")
Crew: 4
Armor: RHAe=720mm (max)
Armament: Mk. 14 105mm ETC smoothbore (36 shells), 12.7mm M2HB MG (coaxial; 2250 rounds), 7.62mm MG (AA; 4000 rounds)
Engine: GD883 diesel, 1500hp (1119kW)
Power/weight: 28.8hp/tonne
Transmission: RK325 hydromechanical automatic, 5 gears
Operational range: 500km (311 miles)
Max velocity: 64km/h (40mph)

Mk.14 105mm ETC smoothbore
Muzzle velocity: 1843.75 m/s
Weight: mount - 3500kg (7716.2 lb); barrel - 1300kg (2866 lb)
Barrel length: 50 calibers
Effective range: 5km (3.1 miles) with APFSDS; 8.5km (5.3 miles) with LAHAT tank-fired ATGM
Shell types: APFSDS, HEAT, LAHAT, HE, HESH (anti-bunker)

That RHAe is very poor, less than even the modern Abrams, which is hardly NS grade, other than that, you have a simple stat block which no details at all. For a look at a modern NS tanks, search for the Nakil, Lince, MCA-7, or LY4A2 Wolfhound.

What is the RHAe of the Abrams?

It varies according to location, but according to this (http://members.tripod.com/collinsj/protect.htm) site, which is commonly cited, it is around 980 on the turret front. Of course, your tank is lighter, which could explain the difference.

My tank being lighter probably is the difference. I could probably get away with more armor, perhaps a total of 1000mm RHAe, since I took the proposed Lince (http://en.wikipedia.org/wiki/Lince_(tank)), lengthened it a bit, gave it a slightly heavier gun and a somewhat heavier engine, and changed out the suspension.

Perhaps it's a 'medium tank'? Poor protection and speed, but a good gun? I'll work up a full MBT in time. Hell, this is more reasonable than saying I've got a tank with similar capabilities to the Nakíl right away. Better that I get there in spurts.

Other than the light armor, is it fine? If I change the armor to 1000mm RHAe, would that be fine?

I would personally class it as a light tank, not because of its weight but rather its protection and main armament. The 105mm is going to have a tough time penetrating the frontal armor of standard main battle tanks even at close range, which means it would have to flank around to the sides or rear to score a kill. You can't really rely on this during actual combat, especially if your enemy uses tanks with main armaments that not only have long-range, but also a high one-hit kill probability.

I could see the tank as a useful one if you added either a standard 120mm gun or other means of killing tanks, such as ATGM's.

You also have no APS nor ERA which makes it even more venerable to enemy missile systems.

To start designing, improving RL designs are a good place to start.

Damn. I was hoping the higher muzzle velocity would allow for proper penetration. I went a step down in gun barrel size to save on weight.

What muzzle velocity would a 105mm ETC gun need to penetrate? Or a 120mm ETC gun? Or a 115mm ETC gun?

I'll probably call it a 'second-tier' medium tank, in parallel with my T-42 Oliver. Both are good for taking on late Cold War tanks, but aren't really able to handle NS warfare. To me, it's too slow for a light tank.

Forgot about ERA. Active protection systems will come later on, when I convert other tanks.

My plan is to convert or adapt failed RL designs, like the aforementioned Lince.

Also, what happened to the Draftroom?

Draftroom still here and active. Our lazy admins just need to approve you, since we get spammed by bots and have to filter those out.

Muzzle velocity needed relies on various different factors, so it's hard to say, really.

That's fine; I'll wait.

Fair enough. At least it's good against light tanks and IFVs and stuff like that. I'll edit the fluff and throw in some ERA.

I like your designs.
If you were to get a storefront up after fine tuning your designs in the draftroom, I am sure you could sell many of your designs. People like me don't have the imagination to design our own stuff so we spend billions, even trillions on foreign designs. I will keep my eye on your designs, and possibly I will buy some stuff.

I've got a storefront (http://forums.jolt.co.uk/showthread.php?t=577616)...
My registration email has still not yet been validated by the Draftroom. I'm being patient, but also a bit annoyed.

Glad you like my designs.

Yeah I wonder how I missed it.

To be fair, it was pretty far back; that's why I've got a link in my signature.
Projects:
SSN, SSK, SSBN/SSGN, SSG, patrol craft, frigates, destroyers, CVS, small carrier, medium carrier, etc.

SSN, patrol craft, destroyer, medium carrier - released
SSK - design phase
SSBN/GN, frigate, small carrier - proposal phase
SSG, CVS - shelved

F-21 Anteater
Designed as a multirole fighter, the Anteater will use a trapezoidal wing with wingspan of ~50' at its widest point. It will have ten external pylons (four on each wing and two smaller pylons on the belly), 2 wingtip hardpoints for AAM-97 Vipers, and a nose-mounted weapons bay for a variety of cannon (or fuel, or bombs). It will be powered using 1 F-119-PW-100 pitch-thrust-vectoring turbofan, which should provide sufficient thrust for this smallish aircraft. It will be about 23m long. It will feature the AN/APG-81 AESA radar, along with the AN/ALQ-144A+(5) IR countermeasure and AN/ALQ-128 & AN/ALQ-56C radar countermeasures. It will include some features (though not maintenance-intensive radar-absorbing materials) meant to reduce stealth.
[Stats to follow, in time, along with a heavily revised description]

OOC: One thing that I can tell you right now, is that for things like the "SAL-49 shipborne air search Lidar," you are going to need more information than you currently have on it. MUCH more information.

Draftroom designs generally have both a statblock, AND a write-up. The statblock generally contains measurements of some sort (length, width, speed, etc.), while the write-up describes how everything works.

NSD is going to DEMAND full statblocks and write-ups, but they will help you by identifying things that need improvement. There are lots of people there who will work with you on your designs, as well. Yanitaria, for example, is damn good at aerospace and small arms; so don't think that you have to design EVERYTHING yourself. Most people actually focus their designs on one area that they are knowledgeable about (Lyras does Army, Yanitaria does aerospace and small arms, Questers does Navy, etc.).

I know that you are annoyed at how long that it's taken for you to get the validation e-mail from NSD, but I would suggest that you resubmit it; and get in touch with Macabees. Mac can be really lazy about doing things, but he does run NSD.

I agree with Lamoni. Before you really get into designs, find something you like, especially where there is a niche, but mostly something you like, and start there. Start designing simple things, and go out and do research. I usually have 30 tabs on mozilla open just to design one airplane, and I take things from various sources, like wikipedia, global security, FAS, Avipedia, and many others. Write about everything you can, everything that makes your design different from existing designs. Describe what it is that you are designing as if you are explaining to someone who doesn't know crap about it. Also, explain the various aspects of the design, like the features of your radar or OLS, what is special about it, and what makes it superior.

It's important to write a lot, even if you don't decide to use it all in your write up. Further, your stat block should be as complete as possible, but don't overload it with useless info. Look at similar designs to decide what is necessary and what isn't.

Thanks for the advice. I know that I haven't included sufficient details yet in my descriptions. I know that I need to improve that. I aim to do so. I just will need to have enough time to do so.

Unfortunately, I'm headed back to college soon, so I will probably have much less time for designing. I'll still try to design stuff on the side (mainly doing research into failed designs and considering what might make them work today), but the pace of design (and of posting in general) will slow significantly until March.

As for a niche, I'm tempted to make my niche 'designs based on or inspired by failed designs.' It's what I've been doing so far, and it creates interesting challenges. More specifically, however, I aim to get into ekranoplans (wing-in-ground effect aircraft) - I know a little about them, they don't appear much (if at all) in storefronts, and there's a fairly wide variety of things one can do with the wing-in-ground effect.

CM-39
Introduction: Inspired by the Advanced Cruise Missile, this weapon is intended to serve as a low-observable long-range subsonic anti-ship missile. Our 3-4-5 design goal was to deliver a 300kg warhead 4000km to within 5m of the target.

Airframe: We have incorporated a number of features into the airframe to reduce its RCS. These range from general features - radar-absorbent paints, a low-power controlled-emission guidance system, and a beavertail nozzle shield to reduce engine emissions - to frontal (sharp nose cone, forward-swept wings), shoulder (chines), and low-frequency (radome-structured fins and wings) RCS reduction. The missile itself is 9 meters long, allowing for more fuel and a heavier warhead to be carried.

Guidance: The CM-39 uses terrain-contour matching and an inertial navigation system. It is fitted with a GPS - though we expect most nations to attempt to destroy GPS systems on the outbreak of war, we also expect that there will be sufficient GPS systems for it to get at least commercial-level accuracy, and that GPS satellites will be cheap enough to launch to ensure the 5m CEP in our design goals. A DSMAC (digital scene matching area correlation) system is also incorporated into the guidance system in the land-attack variant, allowing the missile to correct its course based on previously-taken images. The CM-39's attack profile is low-altitude, low-observable, low-speed, and long-ranged; it remains subsonic throughout its flight, once released from the bomber that carried it.

Engine: We commissioned our subsidiary, Tsien Engines, to design a new turbofan to give the performance we wanted out of the CM-39; they came through with the TE-T-424 turbofan, which generates 4.24kN (432.4kgf; 953.2lbf) of thrust, sufficient to power the CM-39 at speeds of Mach 0.8. Our ship-based and sub-based variants include a small solid-rocket booster to launch the missile.

Warhead: We fitted a 300kg warhead into the CM-39. The land-attack variant can be fitted with a MEPHISTO warhead, which combines a precharge and initial penetrating charge (total of 110kg) to penetrate a bunker or clear soil with a main warhead (188kg) triggered by a variable delay fuse.

Specifications -
Length: 9m
Wingspan: 3.1m
Diameter: 70.5cm
Weight: 1800kg
Max speed: Mach 0.8 (at 50m above sea level)
Range: 4000km
Warhead: 300kg HE or HEAP warhead; MEPHISTO 188kg main warhead (CM-39L); W-80 5-150kT nuclear warhead (CM-39N)
Propulsion: TE-T-424 turbofan, 432.4kgf thrust

Variants: UCM-39 (sub-launched; fins fold out after launch), SCM-39 (ship-launched from Mk.41L enlarged VLS cells; fins fold out after launch), TCM-39 (launched from torpedo tubes), CM-39N (nuclear warhead), CM-39L (land-attack)

Price: CM-39 $700000, UCM-39 $750000, SCM-39 $745000, TCM-39 $725000, CM-39N $1.1 million, CM-39L $800000

Cross-posted to NS Draftroom (http://z4.invisionfree.com/NSDraftroom/index.php?showtopic=5174). Yay!

But that's only if he is not drunk or lazy... I should come on NSD drunk again. Those were the days :mp5:

Anyway, as a suggestion Defense Corporations, if you're going to change your designs as per advice from NSD, it's generally easier to put them there first and then put them on II when (hopefully constructive) criticism has been amended, since you don't have to go back and keep editing it.

I just got on Draftroom now. That'll be how I do everything from now on; I still like showing my future designs here as well. Draftroom-approved designs (all of my designs, from now on, after critique) will get separate threads; I'll update my new designs (as 'block II' or 'flight II' or 'revised due to recently discovered flaws in ___') after they're critiqued on the Draftroom.

F-21 Anteater
Introduction: Our aim was to build a modern multirole fighter. Our design goals were to carry significant external stores at relatively long range in a modestly-stealthy supercruising airframe.

Airframe: We went with a trapezoidal wing, providing the best features of delta wings, forward-swept wings, and standard swept wings. At each wingtip is a hardpoint for our AAM-97 Viper; on the wing itself are eight external pylons. Below the nose is a weapons bay capable of carrying a 20-30mm cannon, a 100kg bomb, or a fuel tank. We incorporated chines - angular features at the nose intended to reduce shoulder RCS, planform-aligned wing and tail edges, a sloped fuselage and canopy, canted vertical surfaces, and a serpentine inlet duct for the engine, along with a signature-assessment system (SAS) designed to inform pilots and maintenance workers when wear-and-tear has degraded the stealthiness of the F-21.

Engine: We went with two TE-T-219 turbofans, an improved version of the engine that which powers the F-22. These generate 15950 kgf (156.4kN; 35163.7lbf) thrust each, providing sufficient thrust to achieve similar performance to the F-22.

Electronics: We fitted our AAR-71 AESA radar, which is a solid-state design resistant to jamming and reception by radar warning receivers due to a high scanning rate. For jamming, we have fitted the AN/ALQ-135(V) active radar jammer and AN/ALQ-144A+(5) IR countermeasure system. The AN/ALQ-99E integrated jamming pod can be fitted, and is standard on EF-21 EW support planes. Finally, our FA-21 fighter-bombers carry the AN/APQ-146 terrain-following radar.
