From the FY24 budget request "FY 2024 funding in the amount of $400.697 million procures 22 M-SHORAD Inc 1 dual Stinger Vehicle Universal Launcher (SVUL) configuration systems to complete the DR. Funding also procures 72 SVULs to retrofit single SVUL configuration systems, Initial Spares, Engineering Services, Contractor Logistics Support (CLS), and Integrated Logistics Support (ILS)" SHORAD Strykers are swapping the unused Hellfire rack for a second Stinger pod.

Economy of scale (34 vs 90 vehicles) and high inflation are a bitch. -

It was acceptable in the eighties is not a great argument for storing ammunition high and forward in the hull on a 'new' vehicle in the twenty twenties. -

I would not consider this an optimal placement for hull ammo storage. -
Nuclear Reactors in Space: For or Against?
Ramlaen replied to LostCosmonaut's topic in Elon Musk: Making Space Great Again
https://ntrs.nasa.gov/citations/20190032344 "A study was initiated to investigate propulsion stage and mission architecture options potentially enabled by fission energy. One initial concept is a versatile Nuclear Thermal Propulsion (NTP) system with a maximum specific impulse of 900 s and a maximum thrust (per engine) of 15 klbf. The system assumes a monopropellant stage (hydrogen), and is designed to also provide 300 lbf of thrust (potentially split between multiple thrusters) at an Isp > 500 s for orbital maneuvering and station keeping. Boost pumps are used to assist with engine decay heat removal and low thrust engine burns, and to compensate for partial tank depressurization during full thrust engine burns. Potential stage assembly orbits that take full advantage of launch vehicle payload mass and volume capabilities are being assessed. The potential for using NTP engines to also generate a small to moderate amount of electrical power is also being evaluated. A first generation versatile NTP stage could enable 8 of 9 upcoming opportunities for short (less than 24 month) round trip human missions to Mars. A second generation versatile NTP is under consideration that could potentially provide a maximum specific impulse of 1800 s at 15 klbf, and enable ambitious missions throughout the solar system. The second generation NTP system under consideration would also allow a choice of volatiles to be used as propellant. This would potentially allow in-situ resources such as water, ammonia, methane, or other compounds to be used directly as propellant by the second generation engine." -
