The most notable change in Type 093 submarine is the disappearance of controlling plane on sub's sail. Previously an unconfirmed blurred image of Type 093 submarine on Internet also corroborates the change. If the Type 093 sub uses "bow diving planes" like U.S. navy Virginia class submarines, the main reason is Type 093 has a smaller "conning tower" with no space for rudder steering gear. PLA navy has known the fact that a decreased sized sub sail can reduce the noise and resistance force when in underwater maneuver.
Besides, the positions of Type 093's sail, rescue buoy and bow antenna is changed. And these changes can be compared with the displayed Type 091A model and other previous photos. Actually, the photo gives a sense that the sail's position is backward than before. And this design also needs bow-diving-plane configuration for greater controlling efficient.
But in the picture, the sub's "conning tower" is even looked to be higher and larger than before. So another possibility is that the photographing angle can not shot the sail dive planes.
A widely sited conclusion is that Type 093 project is assisted by Russian Rubin Central Design Bureau or it has heavy Russian influence. Western analyzers often compare Type 093 with Russian Victor-III nuclear-power attack submarine. Now the Photo clarifies that the Chinese Type 093 has its own characters and its shape-design is close to Royal Navy Trafalgar Class submarine.
Another "VIP" in expo is PLZ-05 155mm self-propelled howitzer. PLZ-05 SPH has a enlarged turret which installed on PLZ-45 full-track chassis. PLZ-05 is a exportation designation of NORINCO in the year of 2002. Most technologies of PLA-05 are from PLZ-04 SPH for PLA Army Artillery. It has been known that PLZ-05's barrel length is 52 caliber and PLZ-04 SPH has a 54 caliber length barrel.
The PLZ-05 displayed on the museum has a commander panoramic periscope on the top of turret and a gunner day/night direct fire sight parallel fitted on gun barrel. Indeed, PLZ-04 SPH is a milestone in PLA Army artillery Digitalization.
Furthermore, the outdoor display in museum also includes JH-7A fighter, Type 99G, New Amphibious Vehicle, DF-25 ballistic missile and other Land& air Warfare System.
