Philippine Modular Launch Vehicle (PMLV):
[ img ]
The PMLV was developed by Philippine Aerospace Corporation (PAC) for the Philippine Space Agency in the late 1990's as a family of launch vehicles encompassing low earth orbit payload capacities ranging from 1500 kg to 25000 kg. After a joint development for a solid-fueled launch vehicle with Israel, which lead to a Shavit derivative (similar to the South African RSA-3) which was used to launch the Philippines' first satellite in 1990, it was decided that a newer liquid-fueled launch vehicle was needed to lift future payloads, including a (then proposed) manned spacecraft. With input the Yuzhnoye design bureau, PAC developed the PMLV to use liquid oxygen and RP-1 for propulsion and developed a series of rocket engines for the launch vehicle. It was decided to use modular design as used by the Atlas V and Delta IV rockets, as these launch vehicles were being designed at around the same time for similar requirements.

The PMLV has several variants (from left to right in the picture above), the PMLV 200, PMLV 400, PMLV 520, PMLV 540, PMLV 600/Heavy and PMLV 400M. All PMLV variants use a common lower stage engine, a vacuum version of which is used on the second stages of all PMLV variants except for the PMLV 200. The PMLV 400, 500 and 600 series vehicles use a Common Modular Core with 5 engines, with the PMLV 200 first stage (with 1 engine) adapted as the strap-on boosters on the PMLV 500-series and the Common Modular Core as the strap-ons on the PMLV 600. The PMLV 400M is a man-rated version of the PMLV 400 used to launch the Philippine Crew Transport Vehicle (PCTV) to low earth orbit.

All PMLV variants are launched from the Mati Space Center near Mati City in Mindanao. The space center has one launch pad for the PMLV 200 and two launch pads for the PMLV 400, 500 and 600 series vehicles, with one of the pads equipped with a crew access tower for manned launches of the PMLV 400M. Vehicle processing of all PMLV variants involves both horizontal and vertical integration. The first two stages are mated at a horizontal integration facility, then loaded to a transporter cradle to be sent to the launch pads on a self-propelled modular transporter. Once on the pad, the stack are pivoted to vertical position and the service structure is rolled to the rocket to allow mating the payload and connecting umbilicals. The service structure is then rolled back before launch.

I notice you are steering away from American-influenced designs toward more international influences and weapons systems

My designs are mostly European in look and electronics fit but are equipped with American and local weapons.

Nice to see more space vessels. The large missiles reminds me the Indian PSLV/GSLV family.

Philippine Crew Transportation Vehicle (PCTV):
[ img ]
The PCTV is a reusable manned space capsule developed by Philippine Aerospace Corporation (PAC) for the Philippine Space Agency (PSA). It is designed to transport a crew of 3 astronauts to low earth orbit destinations such as the International Space Station (ISS) and is launched by the PMLV 400M launch vehicle. Development of the PCTV started in 2004 with several tests on a mockup such as water recovery done in 2006. A test flight article was used in 2008 for a pad abort test and in 2009 for a suborbital in-flight abort test on a PMLV 400M with a live first stage and dummy second stage. In 2011, a unmanned orbital flight was conducted to verify the performance of the capsule in space, followed by another unmanned flight in 2012. The first manned orbital flight was conducted in early 2013 with 2 astronauts. The first mission to the ISS with 3 astronauts was conducted in late 2013.

The PCTV uses a command-service module configuration similar to the Apollo and Orion spacecraft, but features a built-in "pusher" Launch Abort System (LAS) using the spacecraft's orbital propulsion engines attached to the service module. Unlike traditional "tractor" LAS, where the LAS rocket motor is discarded during the flight, the "pusher" LAS is usable during the entire orbital ascent period, which increases safety. Electrical power is provided by 4 solar panels. The control console uses a "glass cockpit" design with LCD touch screens augmented with some buttons for vital functions. To dock with other spacecraft, an androgynous docking port compliant with the International Docking Standard is used. Astronauts riding the PCTV wear space suits designed and manufactured by ILC Dover during launch and reentry. The PCTV is intended for a water landing after reentry, which is conducted in the East Philippine Sea. A specially-built recovery ship with a crane for lifting the capsule out of the water and a helipad for accommodating a helicopter to fly the astronauts back to shore is used for recovery operations.

Very nice, now we need to see the recovery ship.

Ambitious undertaking for a country of a size of Philippines in that timeline (even in AU environment), but of course a nice drawings.

If Elon Musk was able to make a successful rocket company which started as just another commercial space start-up in 2002, then why not for the Philippines in my AU, whose space program started in the 1970's with Israeli and later, Ukrainian assistance?

Philippine Modular Launch Vehicle - Reusable (PMLV-R):
[ img ]
The PMLV-R is the (partially) reusable version of Philippine Aerospace Corporation's standard PMLV. It features a reusable first stage equipped with landing gear, RCS thrusters and fins that allow it to return to the launch site. The reusability features are similar to those used on the SpaceX Falcon 9 but differ in the landing gear and fin design. This system allows for a reduction in costs when compared to expendable launch vehicles. The PMLV-R has slightly less payload than the standard PMLV 400 and 600 due to the equipment added to make the first stage reusable. The manned PMLV-R has the same height as the standard PMLV 400M, so that the existing white room for crew access to the rocket while on the launch pad could still be used.

Updated Philippine Naval Aviation chart:
[ img ]
Added the Philippine Aerospace Corporation (PAC) EC-1 in AEW&C and Tanker/COD variants, which is a STOBAR-compatible carrier-based aircraft developed to replace the E-1 Tracer and C-1 Trader in Philippine Navy service. The Sea Gripen is also a modified version, which in this AU is a joint development between Saab and PAC (as with the JAS-39E/F) and is fitted with a thrust vectoring Eurojet EJ200 engine and some Philippine-specified systems.
