Hello Ethan,

Thank you for the suggestion and I did try using the MRL sequence. A single 80 mm MRL tube, if I followed the direction correctly, has a weight of 1.65 kg, a volume of 0.0413 m^3, and a price of Cr1,300.

A 7 tube 80 mm rocket pod's weight is 11.55 kg and the 19 tube version is 31.35 kg.

I live near what is now know as Joint Base Lewis-Mchord and I've had the opportunity to look at the rocket pods attached to the Apache. The pods have frame that the tubes mount into with a skin covering the outside. The enter assembly was mounted on a hardpoint.

Oops, Ive got to go I have driving duties to perform for my Mom, thank you again for the suggestion.

Tom, I'm not sure that the missile launch tube design sequence translates directly to rocket pods. Maybe I'm misinterpreting. I'd look at multiple rocket launchers (artillery) as a possible closer equivalent. There's just a difference between a rocket pod for aircraft use and a ground mount for launching a guided missile. The tube launchers in classic striker assume that you need some sort of support to hold the tube, while rocket pods are supported by the rail, which has its own weight and cost. There may be some errors and inconsistency use in the design rules. I do think that the pricing maybe off for rocket pods compared to real world prices. The main problem with real-world aircraft rocket pods is that high subsonic and supersonic designs are quite different from ground mount rocket launchers. I'm not sure if there is a design sequence anywhere that addresses this adequately. Also, I can't remember what the supposed equivalent is between Traveller credits and current US dollars.

Morning from the Pacific Northwest,

 

My pondering worked over night resulted in determining that t

he MT: COACC Rockets Table on page 69 lists the range of the 120 mm rockets as 1,500 m which in CT Striker DS 9 calculates the propellant weight to be 30 kg. Bumping the range up to 2,000 m requires 40 kg of propellant. Adding the 20 kg warhead puts the weight at 60 kg.

 

Unfortunately, that does not correct the weight and cost of the 120 mm 3 tube rocket pod or the 120 mm launch rail cost using DS 9 Step B. Launchers directions.

 

The cost for the three pods are not consistent based on CT Striker DS 9 which has the cost as Cr 100 per tube. The 80 mm 7 tube pod appears to have a cost of about Cr 5.8 per tube, an 80 mm 19 tube pod’s cost is about Cr 4.8 per tube, and the 120 mm 3 tube pod has a cost of about Cr 1.8 per tube. Checking TNE FF&S the tac missile rules are not quite identical and T4 FF&S does not appear to have any launcher for non-space missiles.

 

Does anyone know how to contact any of the people who wrote MT: COACC which might help clear up my confusion?
